Species tulips for every garden - plant some today!

Species tulips may be smaller than hybrids, but they are also tougher - and create a stunning show year after year. There is a species tulip that will be happy in every garden - even clay! so there is no excuse not to add these lovely bulbs to your planting scheme...


Tulips are often considered ephemeral in the garden, and it's true that many hybrid tulips decline in vigour after the first year. Species tulips, however, are reliable year upon year, often naturalising and setting seed to produce drifts of flowers that actually improve over the years.

Species tulips tend to be smaller and less showy than their hybrid counterparts but they are equally heart stopping. The flowering season begins on early March just as the garden is waking up from winter, but there are varieties that bloom in succession all the way through until the end of May. From the creamy drifts to Tulipa turkestaica to be the lipstick-red of Tulipa fosteriana, it really is worth making room form these little beauties in your garden.

As a general rule, good drainage is essential for all tulips. Although they love to be watered during their growing season, most species tulips prefer dry soil over the summer months. Rock gardens have typically been the best place to grow species tulips because they emulate their natural habitat in the wild, but they are not the only situation in which these diminutive gems will flourish.



Pots and containers
Tulipa greigii starts flowering in March. The dwarf flowering habit and large decorative leaves make for stunning displays in window boxes and containers. Try combining Tulipa greigii 'Red Riding Hood' with winter pansies and trailing ivy for a late-winter show stopper. Try also T. humilis 'Persian Pearl' and T. kauffmanniana 'Heart's Delight'

Clay soil
Tulipa acuminta is an usual and exotic-looking tulip with needle like pointed petals of red and yellow. It is a surpise hit in clay soil, flowering in May, and is excellent for cut-flower arrangements.
Low-growing and early-flowering, Tulipa humilis is equally happy in a rock garden, a raised bed, sunny border or a pot. It has delicate, blade-like leaves, and is available in a wide range of colours.
Tulipa turkestanica is one of the easiest species tulips to grow, and deserving of a place in almost every garden. The elegant creamy-white flowers have a rich yello centre, and really brighten up the winter garden. These tulips will spread gradually and reliably to form dense patches of small starry flowers.

Woodland edge/semi-shade
Tulipa sprengeri is the exception to the rule: flowering in late May and early June, it actually prefers slightly moist soil - and even a bit of shade. try including it in woodland-edge planting schemes, or use it to underplant deciduous trees and shrubs. Don't be put off by its price: Tulipa sprengeri sets seed widely and will soon become an established accent in the garden.

All rounders
With its sturdy stems, broad leaves and huge bright red flower which can be 15cm across when fully open - Tulipa fosteriana is one of the most popular species tulips. it adapts to a wide variety of soils and situation, relishes neglect and reliable each year.

Clever with clematis

Stunning on its own, this climber works even better teamed up with trees and shrubs for a dramatic second burst of colour.

We are used to pairing clematis with roses, but there are hundreds of other combinations to be explored. Many plants offer limited interest for long periods of the year, so why not extend the season by partnering established trees and shrubs with a clematis?

Buddleias are great with the lavender-blue Clematis ‘Arabella’ or the dramatic dark-purple ‘Miranda’. Both cultivars flower non-stop from spring to late summer and will actually benefit from any hard pruning your buddleia requires to keep it in check. Other silver-leaved shrubs such as Garrya elliptica gain from an association with Clematis viticella ‘Palette’, which has delicate purple-veined flowers fading to white at the centre.

Clematis 'Crystal Fountain' is a daring choice with Ceanothus

The purple foliage of Cotinus ‘Royal Purple’ or Cercis canadensis ‘Forest Pansy’ provides a dashing contrast for Clematis ‘Wisley’ or the late-flowering white Clematis ‘John Huxtable’, but can also marry beautifully with the soft pink of ‘Comtesse de Bouchaud’. In fact, the list of possible combinations is almost endless. The golden rule to remember is that the most successful partnerships have the same pruning requirements.

The line of beauty

Garden designer Alice Bowe at work in the border

The main borders combine traditional herbaceous perennials with swaths of ornamental grasses and plenty of roses. I have inherited my mother’s love of old-fashioned roses, so I squeeze in as many as I can. I am particularly interested in designing planting with the relaxed painterly look of a traditional herbaceous border without the intensive maintenance – and this is where I try out my ideas to see what really works.....

Photo by Jenny Lewis

This year, we have been attacked by slugs in their thousands and I have taken the opportunity to experiment with aromatic substitutes for some of my favourite border perennials. As a result, I have discovered a new favourite in Teucrium hircanicum, which has, this year, replaced Salvia nemorosa ‘Schwellenburg’ in the Nottingham borders. I am becoming almost evangelical in my promotion of Agastache. But my best discovery this year is a waste product from the rooibos tea industry, called Fine Naturals, that is brilliant at deterring slugs.

Green Manure can save you a fortune on compost

Autumn is on the way, and it’s a good time to think about making new beds. More dauntingly, you may have just taken on a whole new garden or an allotment. As you dream longingly of friable loam, your spade invariably hits builders’ rubble, free-draining sand or compacted clay. While there is little choice except to dig out builders’ rubble, there are more options when it comes to the task of enriching the soil. Recycled green waste, animal manure and spent mushroom compost are popular additions, but before you start despairing at the cost of lorryloads of compost, don’t forget the cheapskate’s alternative: green manure.

Green manures or cover crops are an inexpensive way to improve both the structure and nutrient content of your soil. Cultivated primarily to add organic matter to the earth, a green manure crop is usually grown for a specific period (say six weeks, or over winter), and then chopped down and incorporated into the soil. They are a great option when preparing new land for use – forming a green carpet that stops weeds colonising and prevents nutrients from being washed away. Some varieties, such as lupins, fodder radish or alfalfa, even help to give the soil structure because their fibrous tap roots break up the subsoil.

Traditionally, green manures have been used on arable land or allotments, but they are equally useful in gardens. All you need is a packet of seeds, a spade, and patience while they do the hard work for you.

Green manures consist of legumes and non-legumes. Legumes are popular for their ability to fix nitrogen: once the green manure has been dug into the soil, this nitrogen becomes available for future plantings. Non-legume plantings, however, often produce more organic matter. They have a better root system and so are better suited to surviving extreme weather conditions and poor soils. There is a green manure for every ailment: red clover suits sandy soil; field beans and grazing rye are excellent in clay; lupins improve the substructure of the soil; while the best choice for dry soil is alfalfa.

Fast-growing, leafy green manures are often recommended for gardens because they provide the most nutrients when dug into the soil. Just remember, if you are preparing soil to grow vegetables, your green manure should not be closely related to the plants that are to follow. For example, don’t use legumes such as field beans if you are planning to grow runner beans or garden peas afterwards. This reduces the likelihood of disease.

Although many green manures can be sown all year round, it is ideal to sow them in the autumn to overwinter, as vegetable plots are generally empty and people are spending less time in their gardens. Try sowing fast-growing fodder radish or mustard in early September so that it can be incorporated in late October. Alternatively, cut down and chop up the green manure in late October and leave it on the surface as a mulch.

Italian ryegrass and Hungarian grazing rye can also be sown in September because they are very hardy. Leave them growing all winter before being dug in during spring to release nutrients as they rot. If you are growing your green manure on clay soil, however, it’s best to dig it in during autumn. Alfalfa is another good choice for an overwintering green manure. This nitrogen fixer should be dug in during the spring.

Before sowing your green manure, the site should be roughly dug over and weeded. The soil needs to be firmed by lightly treading it down, and then your seeds can be sown in rows about 6in apart, or broadcast and raked in.

All green manures should be dug in while the stems are still soft so that the plant can break down easily. It is a good idea to chop up the green manure and allow it to lie on top of the soil for a few days. It should then be dug in to a depth of about 6in. Your soil should be ready for planting only a couple of weeks after incorporation.

Green manures are often overlooked by gardeners looking for a quick fix, but used wisely, they can play an important and cost-effective role in the establishment and maintenance of a garden.

OVERWINTERING

Hungarian grazing rye. One of the best green manures for winter use. Sow in August/September, or as late as October in the South. A good cover crop to prevent nutrient-leaching. Dig in during the spring.

Field beans. Very hardy, with deep nitrogen-fixing roots. Suitable for overwintering.

Fodder radish. Deep tap root brings up nutrients from the subsoil, and produces plenty of organic matter. Over winter it will gradually die down, making it easy to incorporate into the ground in spring.

UNDERSOWING AND INTERCROPPING

White clover. Low-growing for ground cover and intercropping between rows of vegetables. Use as a living mulch or long-term green manure.

Trefoil. Shade-tolerant and low-growing, so great for undersowing. Sow between March and August and it will stand through the winter into the following season. It does not like acid soil but will tolerate some shade and is suitable for undersowing, for example between rows of sweetcorn. When the corn is cut down, the trefoil will grow to protect the ground over winter.

MULCHING AND WEED CONTROL

Crimson clover. A vigorous, quick-growing clover with wonderful red flowers, which bees love. Sow April-September. Not normally winter-hardy because it dislikes waterlogged and heavy soils.

LONG-TERM GREEN MANURES

Alfalfa. Rich in calcium and the major elements – almost a complete natural fertiliser. It is very deep-rooting – improving substructure and bringing trace elements to the surface. Sow April to July. Can be turned under in the autumn or left to stand through the winter.

Bamboozled

Everyone loves elegant, architectural bamboo, but choose the right one or you could end up with a jungle...

Bamboo is one of those plants that people both desire and fear. They desire it, because it’s lush, jungly and instantly architectural in a way few other plants are, but it can also be invasive, so it’s unwise to head off to the garden centre without doing a bit of research beforehand. If you’re going to plant an invasive type, you need to surround it with root barriers.

So which bamboos are invasive and which not? There are two main types, depending on how their rhizomes grow: runners and clump-formers. Runners can be difficult to control as their long underground rhizomes will always try to colonise new areas. They include Sasa, Pleioblastus, Sasaella and Phyllostachys. Clump-forming bamboos tend not to be invasive and include Fargesia, Bambusa and Chusquea.

Although gardeners have worked out how to manage the spread of invasive bamboos, we are just beginning to understand the wide range available. A few years ago, the main trend among garden designers was for black bamboo. With this now established as a firm classic in the planting palette, designers are starting to expand their repertoire of plants. Lime culms (canes) such as Phyllostachys viridiglaucescens are particularly fashionable at the moment.

So why do garden designers love bamboos so much? Partly because they are evergreen, they create strong architectural structure all year round – hugely important in urban gardens. In a small space, they provide volume and drama, and they grow amazingly fast – new shoots can put on 10-15cm a day in the growing season. Yet they don’t block out the light, which means they make great screening plants.

If privacy is your principal concern, think about Phyllostachys nigra, which is very narrow but tall and so doesn’t take up too much space in small gardens. Besides ugly views there’s the issue of ugly noise, and the gentle sound of wind rustling through bamboo can block out both traffic and neighbours even more effectively than a water feature – with the bonus of being much lower maintenance than water. The other great advantage of bamboo is that it can provide strong foliage in a shady garden – Fargesia is particularly good where sunlight is limited.

Those are the basics, but designers will often create sophisticated effects, particularly with the shadows of bamboos – the light foliage creates great dappled effects in sunlight, or dramatic contrast under artificial lighting. In winter, the stems of bamboo can provide a feature in the same way as dogwoods. Try Phyllostachys aureosulcata f. aureocaulis, whose golden yellow stems blush pink in strong sunlight.

So how do you integrate bamboo into a planting scheme? First, look for a variety with plenty of good foliage. Try Phyllostachys bissetii, which is a fresh green even in midwinter, and surround it with flowers as punctuation points.

My favourite bamboo garden, la Bambouseraie in the south of France, can still teach us a thing or two about how to use bamboo in the landscape. Pleioblastus pygmaeus can be clipped to form a low-maintenance hedge, a bit like box, and Sasa forms a wonderful weed-suppressing groundcover. For inspiration closer to home, visit the Bamboo Garden at Kew, the Eden Project in Cornwall or the Bamboo Labyrinth at Alnwick in Northumberland.

CANE MADE PLAIN

Grow in your garden

Select the position for your bamboo carefully. Most bamboos prefer full sun but if you need a bamboo for a shady spot, a Fargesia is ideal.

Some bamboos, as you are probably already aware, are rampant spreaders and so it is important to contain their roots. Line the planting hole to a depth of just over half a metre with paving slabs or a specialist rhizome barrier (available from all good nurseries). Don’t make the mistake of using a pond liner as the roots will easily pierce it. Remember that bamboo roots can arch over low barriers, too, so make sure the top extends at least 3in (8cm) above ground level.

Try: Phyllostachys nigra, Fargesia denudata, Fargesia rufa, Phyllostachys aurea

Grow in pots

Another option when growing invasive bamboo is to grow it in a container of at least 18in (45cm) in diameter. Make sure the pot has good drainage, and keep your bamboo well watered at all times to ensure strong growth.

Try: Phyllostachys nigra, Sasa or Pleioblastus variegatus

Wildflower Meadows

Over the past 60 years, 95 per cent of our wildflower-rich meadows have been lost, mainly due to changes in farming practice. Creating small areas of wildflowers in your garden not only attracts wildlife and increases biodiversity, but also provides an area of sumptuous beauty. You can create a meadow in your garden with only a few square metres with which to work. The key thing to remember is that wildflowers respond best to hardship and trauma, so impoverished soil is a must.

The first thing to do is reduce the fertility of the soil. This can be achieved by scraping off the topsoil, or by importing a substrate of hard core (builders’ rubble or old broken garden bricks, for example), crushed limestone (available from builders’ merchants) or fine gravel laid on top of a weed-suppressing geotextile. Immediately stop fertilising the area, and either this month or next month sow a wildflower mix that suits your soil type and situation. To make it easier to broadcast your seeds evenly, try mixing them with silver sand. Sow half your seeds lengthways and half widthways, rake in lightly, water thoroughly and leave them to grow. Do not fertilise.

If you are stuck for inspiration regarding which wildflowers to grow, find out which varieties naturally flourish in your area, or use the Postcode Plants Database at www.nhm.ac.uk/science/projects/fff; it generates lists of native plants for any specified postal district in the UK. Where possible, obtain seeds of British origin, grown by wildflower seed companies on their own land. Cut your meadow at the end of the summer, remembering to rake up and remove all debris. Be prepared to manage your meadow in subsequent years by removing any dominant thugs, incorporating further sowings and supplementing with plug plants.

Bear in mind that traditional wildflower meadows can take many years to establish. But for those who don’t have quite that level of patience, there are a couple of cheats and shortcuts available. The first is to sow a Pictorial Meadows seed mix. Developed by Dr Nigel Dunnett at the University of Sheffield, these mixes have been carefully blended from native and non-native hardy annuals to provide a long season of cost-effective and painterly “meadow effect” displays. They overcome many of the problems associated with creating meadows from seed and are perfect for creating flower meadows in the garden. Unlike most wildflower meadows, the success of these mixes is largely down to good ground preparation and good soil fertility. My favourite blend is the annual short mixture, which contains California poppies, larkspur, love-in-a-mist and cornflowers, and which flowers all summer long with glorious intensity.

Or, for an “instant” wildflower meadow, you can buy rolls of pre-seeded felt that you lay just like a carpet. This biodegradable material is the ultimate low-fertility medium and acts as a barrier against pernicious weeds and other more aggressive grasses that would normally stop wildflowers from taking root. The felt also retains moisture, helping the wildflowers establish quickly in the soil below. The British wildflowers in this product have been selected to provide a colourful display and a prolonged flowering period, although you can order a bespoke seed mix if you prefer.

Two Timers - Bimodal climate change survivors

Alice's article about planting for climate change has been published in this months Garden Design Journal. Read more about bimodal plants that can ride the storm.

With changing weather patterns, designers may need to consider a palette of plants that are able to cope with more than one extreme.


The capricious weather we have been enduring over the last few years has highlighted the need for a new approach to our planting choices. In the past we could identify gardens as 'boggy' or 'dry' with some ease, and then plant them accordingly, but things are becoming less and less predictable. Weather extremes of flood and drought can both occur in the same garden within a short period: often without warning. If we can no longer rely on the accepted weather cycles of previous years, we must take action to adapt our planting designs to cope with the unpredictable impact our volatile weather may have on growing conditions.

In recent years we have all become experts in drought tolerant planting, but for the unpredictable weather challenges ahead we will need to develop a sophisticated arsenal of bimodal plants: that is, plants which can cope with more than one type of weather extreme.

Interestingly, plants that typically grow in moist habitats often survive suprisingly well in drier soils (so long as the soil is reasonably fertile) but the opposite is rarely true. Plants that are adapted to dry conditions often do not cope with flooding and waterlogged soils.

In fact, as a general rule, all grey and silver leaved plants hate flooding. This includes drought tolerant plants such as senecio, buddleja, echinops, eryngium, thyme and lavender. Therefore it is best to avoid using all of these mediterranean plants unless they are in planted in pots or raised beds, or have excellent drainage.

Beech and Cherry trees are known to be particularly vulnerable to flooding, so a sensible stormscaping choice would be to substitute them with storm proof alternatives that offer similar visual characteristics. Why not try using hornbeam as an alternative to beech for trees and hedges, as this tolerates wind, drought and flooding. As an alternative to the cherry tree, why not plant amelanchier: whose clouds of spring blossom are unrivalled in my garden. Amelanchiers also provide exquisite autumn colour – and if planted as a multi-stem specimen can act as a mini windbreak. An alternative source of storm proof autumn colour can be found in the form of the vibrantly coloured Liquidamber styraciflua or Acer saccharinum. – both of which tolerate extreme of flood and drought with some ease.

Few trees, except the large swamp Cyprus (taxodium distichum) can tolerate more than one month of submersion during the growing season but as a general rule, broad-leaved trees tolerate flooding better than conifer trees. Try alder (Alnus) river birch (Betula nigra) hornbeam (carpinus) willow (salix) and ash (fraxinus) for your best chance of success.

Most woody shrubs are not any better adapted to flooded conditions than trees. Common casualties of extreme weather conditions include Forsythia, Daphne, Camellias and Yew: who simply panic in waterlogged soil. These can be grown in a pot, or substituted for plants that can more effectively tolerate volatile weather conditions.

We can probably all think of a few ’hard as nails’ shrubs, such as Fatsia japonica and Viburnum tinus, that can tolerate almost anything you throw at them but wouldn’t it be boring if these were our only options for stormproof shrubs. Cercis Canadensis, one of my all time favourite planting choices, is surprisingly storm tolerant – and can cope with long term drought as well as a good few days of standing water. Hibiscus moschetos is another fantastically elegant shrub that is suspiciously hard to kill!

Cornus mas and Berberis thunbergii are two other shrubs commonly reported to be tolerant of flooding: even during the growing season. An ideal storm and flood tolerant plant partner for your cornus would be asplenium, Liriope, Aquilegia or dryopteris filix mas. Convallaria majalis is another woodland perennial that survives both drought and flooding but it is remarkably invasive and can be hard to control in a planting scheme so it is a less ideal choice on a domestic garden scale. Avoid hellebores and tiarella entirely as they so not cope well with waterlogged soil.

My ‘wonder plant’ award must go to the ornamental grasses – specifically Calamagrostis x acutiflora ‘Karl Foerster’. This wonderful grass is a deserved favourite amongst garden designers, and it is easy to see why. This plant seems to cope with almost anything I throw at it. It will happily grow in saturated soil and standing water . It copes effortlessly with drought and is tolerant of extremely acidic soils. It will return to a stiff upright position after having been bent flat to the ground by 80mph winds and it will stand strong through a soggy winter. My other stormproof favourite is Panicum virgatum: especially ‘Northwind’ and ‘Strictum’ which offer similar ‘superhero’ characteristics, but a softer effect.

Bulbs notoriously hate to be left standing in water, especially Eremurus, and are likely to rot away in waterlogged soil. In gardens where flooding is a prevalent threat, you may be better to plant your bulbs into pots in the autumn and treat them as seasonal bedding to get round this issue: planting them out into the border just a few weeks before they are due to flower. In gardens that only suffer from minor waterlogging, try Camassia - which originates from the moist meadows of North American prairies.

Although flooding is a natural event that can’t be prevented, you can be prepared for it. We all know that organic matter is the key to improving soil performance in drought conditions but did you realise that good soil preparation is also key to defending your garden against the ravages of flooding? Organic matter helps bind clay soils into crumbs, so that water infiltrates more quickly after a downpour. Improving the soil structure also makes water more easily available to plant roots, which can grow through gaps between the soil particles.

You can also help to prepare your garden for storms when you are planting and pruning specimens. Plant small and water deeply to encourage deep roots. These will not only anchor the plant and help it cope with strong winds, but will provide a vital connection to the water table deep underground. Choose multi-stem specimens where possible as these will act as a miniature shelterbelt and help to slow down racing winds.

There are other ways to cheat the weather with plants that are less tolerant of rough and volatile conditions. Drought tolerant plants which are not inherently wind tolerant can be pruned to make them tolerant of wind. Sedum, for example, can be cut back by half in early June – to about 4 inches, or pinched to control its height. I have found this very effective in my windy Midlands garden and my sedum stand strong and structural all through the winter where they used to flop and flail.


We are only just beginning to learn how to garden in a changing climate and I am sure we will continue to be surprised at just how quickly plants adapt to new environmental conditions. For the moment, if we just think a little harder about how we can plan our planting choices to stand up to the unpredictable - and experiment to push the boundaries of our existing knowledge.

New Plant Introduction - Echinacea 'Green Envy'

Echinacea 'Green Envy' has exceptionally long lasting green flowers and will happily bloom from July to October. Although I usually prefer the more elegant long thin reflexed petals of echinaceas like 'pallida', this new plant introduction has stolen my heart.

I am a big fan of green flowers, and this echinacea is a welcome addition to my planting design palette.

The broad-petalled blooms have a suprise in store. Although they open green - they turn magenta from their centres outwards as the flowers age through the season.

Drought tolerant and great for cutting, this plant will reach a height of about 80cm

Snowdrop season - gardens to visit

A colourful garden border need not bust the bank; start from seed

Making a garden can be very expensive. People often embark on a makeover after moving house, when money is tight, or they splurge on landscaping and then realise they don’t have enough left over for plants, but it is surprising how frugal you can be if you plan ahead and are prepared to spend time raising your own plants. The easy answer is to sow a wildflower mix evenly across the entire bed. A more challenging solution, and the one I am going to talk you through here, is to sow a composition that produces flowers in the first year but includes a balance of perennial and annual plants so that your garden will become less labour intensive every year.

For my plot I’m using a 5m by 2.5m patch of ground, with good sun and drainage, but the plan can be adapted easily if you have more space. The plot has a fence at the back of it and forms part of a larger garden, and the plants I have chosen are fairly well behaved. The planting is free-flowering and painterly.

VALUE FOR MONEY

When most people think of growing plants from seed, they think of annuals, but there is a large variety of perennial plants you can use. Perennials represent better value for money because you don’t need to re-sow them every year, and, if grown from seed, are less expensive than if bought as young plants from a garden centre. One of the main structural plants in this scheme is the perennial Achillea millefolium ‘Cassis’. This produces immense flat plates of intense cherry red flowers over a very long period and has a strong winter skeleton. I have repeated the Achillea in clumps throughout the scheme to bring continuity and cohesion to the composition. Repetition is important in any scheme as you will see by my continued use of it here. Echinacea also has wonderful structural forms and produces large seed-heads that will give the border real strength and interest in the winter months.

I have also chosen a couple of climbers to provide height and structure at the back of the border. These are both annuals and ramble up home-made tepees constructed from bamboo or hazel (or other garden prunings). Lathyrus odoratus ‘Wiltshire Ripple’ is a richly scented sweet pea that blooms over the summer months and Nasturtium tropaeolum majus ‘Jewels of Africa’ is a variegated climbing nasturtium with attractive marbled foliage. Although included for its long season of colour, the leaves and flowers of the nasturtium are edible and can be used to add spice to salads.

SHOW-STOPPERS

Atriplex and fennel are favourites among garden designers. Both bulk up early in the year and work as excellent foliage fillers for juvenile plantings. The other plant I have included for its textural qualities, Panicum (switch grass), is slow to bulk up but is worth the wait. Its foliage will balance the brighter flowers in this scheme. For the first year or two, I would recommend sowing extra digitalis in a spare bed, or indoors, so that you can plant them out as bedding among the switch grass seedlings in May.

With the backbone of new planting in place, we can turn our attention to the show-stopping annuals and perennials that will fill out the border. These include the spring-flowering Viola cornuta nigra ‘Bowles Black’ and the long-lasting clouds of Cosmos bipinnatus ‘Sonata White’. Also fighting for attention are tall velvety sunflowers, the sumptuous skirts of black poppies and colourful wallflowers. Many of the plants, including the long-flowering Verbena bonariensis and my star plant, Verbena hastate, will attract butterflies, which will only add to the display.

GROW YOUR OWN

For the best results, follow this step-by-step, month-by-month guide, and then sit back and enjoy

February/March

Sow in a windowsill Achillea millefolium ‘Cassis’, Aquilegia vulgaris ‘Nora Barlow’, Echinacea purpurea ‘Magnus’, Malva ‘Zebrina’, Panicum virgatum, Verbena bonariensis and Verbena hastate.

Sow seeds on the surface of lightly firmed, moist seed compost in a propagator.

Cover seed with a light sprinkling of compost or vermiculite and keep the compost surface moist but not waterlogged.

The exceptions are Viola cornuta nigra, which likes dark conditions for germination, so make sure you exclude light, and Erigeron, Dianthus and Papaver orientale, which germinate best if the seed is not covered with soil.

If you do not have a propagator, try sealing your plant pot or tray inside a polythene bag until after germination. I use small heated windowsill propagators that have seven compartments but come in all shapes and sizes.

The best way to check that you have watered your seeds correctly is to place a dry finger on the soil. If soil sticks to your finger, you’ve got it right. If no soil sticks to your finger, you need to add more water.

March

Prepare the soil by weeding thoroughly and digging through some leaf mould or mushroom compost before raking the bed to create a fairly level surface.

With a tool or stick, make a furrow to a depth of about 2cm, then sow your seeds, dropping them in 5-6cm apart.

After sowing, cover your seeds by pulling soil over your furrow. You want your seeds to be 5-6cm deep, so move just enough soil to fill in your trench without creating a mound over the seeds.

Use a watering can or hose with a diffuser attached to water the seeds. Sprinkling the water like a rain prevents it from washing away the soil.

Sow direct into the garden Atriplex hortensis cupreata, Cosmos bipinnatus ‘Sonata White’, Foeniculum vulgare, Helianthus annuus ‘Velvet Queen’, Lathyrus odoratus ‘Wiltshire Ripple’, Tropaeolum majus ‘Jewel of Africa’ and Papaver paeoniflorum.

Late March

Your seedlings should be large enough to handle so transplant them into 7.5cm pots or trays.

Gradually acclimatise your plants to the outdoors for 10-15 days by placing them in a cold frame or using a greenhouse. Once the risk of frost passes, plant them out.

If you don’t have a cold frame, you can make one out of a plastic storage box and a sheet of perspex. Rest the perspex on top of the box at night to keep in the warmth and during the day turn it 45 degrees for circulation.

April

Clean your propagator and then sow foxgloves in it and leave indoors.

The seeds sown straight into the ground outside should have germinated by now, so thin them to their correct spacing.

Erect tepees as climbing supports for the sweet peas and nasturtiums.

May

Plant out Digitalis seedlings into the garden.

The hard work’s over. Enjoy!

Planting Design for a twilight garden

Integrate light blooms in your planting, and see the twilight garden come alive.

It’s frustrating for many of us that we only return from work as the light is fading or almost gone, aware of all the perfect garden moments that have slipped by while we were stuck at the office. However, with a little planning, it is possible to create a garden that is at its peak at dusk – welcoming us in a cloud of fragrance as we open the back door.

White, grey and silver are colours that appear to glow at dusk: an optical effect that results from the ability of these colours to bend invisible ultraviolet and infrared light into the visible spectrum. In giving back more light than they receive, white, grey and silver plants appear to effloresce.

White and pale-coloured plants also tend to be the most fragrant, and it is always worth including a selection of these night-scented treats in your garden. Jasmines such as J. officinale and J. polyanthum are best grown against a house wall where they will benefit from the retained heat of the bricks, oozing a rich heady scent in the evenings. This provision of scent close to the house can be continued throughout the year, perhaps with a winter flowering honeysuckle and pots of lily of the valley, hyacinth and tobacco plants. By integrating fragrant white blooms and silver-leafed aromatics throughout the planting scheme, you can create a scented garden all year round.

The delicate, aromatic foliage of grey and silver-leafed plants such as lavender and artemisia provide the backbone of the planting and can be complimented by more structural forms, perhaps Melianthus major or the biennial sea holly Eryngium maritimum ‘Miss Willmott’s Ghost’. Other silver plants include the non-flowering lamb’s ears Stachys byzantina ‘Silver Carpet’ or the wonderful, silvery Convolvulus cneorum.

Concentrated daubs of white can be used to draw the eye and as a striking focal point. You can achieve this effect by grouping together plants with large, white flowers such as Lavatera trimestris ‘Mont Blanc’ or Hibiscus syriacus ‘Diana’, whose flowers stay open at night.

White flowers with an airy texture work in a different way, creating a misty, romantic feel when dusted by frost and dew. Cleome, Gaura lindheimeri and gypsophila work effectively as a subtle introduction to larger white blooms. The best effect is gained by sparing use of white within a matrix of grey and green foliage. The darker greens, greys and silvers of the foliage form a strong background against which the white can shine, as well as serving to separate the multitude of white shades that appear in nature.

It is worth avoiding plants with white blooms, whose dead petals cling to the plant, such as roses and the white form of lilac. Superior choices include spring-flowering snowdrops, the white flowering bleeding heart Dicentra spectabilis ‘Alba’ and tulip ‘White Triumphator’. These could be followed in summer with Geranium ‘Kashmir White’, white foxgloves and the fluffy clouds of Crambe maritima, plus the sweet scents of the tobacco plant Nicotiana sylvestris and a mock orange Philadelphus ‘Belle Etoile’. A wilder autumnal aspect could come from the translucent grass-like molinia and the pale spires of Veronicastrum virginicum ‘Album’, before rambling into the ghostly elegant bramble Rubus thibetanus and a sweetly scented virburnum at the year’s end.

With so many plants to choose from and so few precious daylight hours in the garden, a moonlit garden never seemed more appealing.

Gardening is like matchmaking: some plants just go together

The essential beauty of the snowdrop lies in the linear perfection of the single bell. Classically, they are planted in sweeping drifts beneath deciduous trees, demonstrating the awesome power of repetition. But they can also be used in stunning modern combinations. Of the 500 varieties of snowdrop (yes, really), Galanthus nivalis and Galanthus elwesii are the most common. They'll go with anything. Those with double bells need a bit more thought.

1 With Black Lilyturf: Galanthus gracilis, Ophiopogon planiscapus 'Nigrescens'

This contemporary design classic of pure white flowers emerging from matt black strappy foliage exploits the drama of tonal extremes. The slender, linear thrust of Galanthus gracilis punctuates the black grass and lifts an otherwise dark, flat scheme. You could also use Galanthus ikariae (which is more suitable for drier situations) or my favourite, Galanthus 'S. Arnott', which flowers freely and increases easily. In the autumn, it's worth planting some tulips — I like the maroon Tulipa 'Recreado', which creates a suspended sea of colour against the black, once the snowdrops are over.

2 With red-stemmed dogwood: Galanthus 'Atkinsii' with Arum italicum 'Marmoratum' and Cornus alba 'Sibirica'

A haze of bare red stems draws the eye from a distance, but close up the combination of red Cornus against green foliage can appear brutal. Snowdrops — in this case Galanthus 'Atkinsii' — break up the harsh contrast. Plant a milk-white Narcissus ­ triandrus 'Thalia' — for later.

3 With an architectural grass: Galanthus 'Atkinsii' and Stipa tenuissima

The bright dots of 'Atkinsii' bells appear to hover above Stipa tenuissima, as their stems disappear into the coat of grass. Catching the breeze, the Stipa shifts between an opaque mass and a transparent screen, peppered by the white points of the snowdrops. A smaller variety could get lost, but Galanthus 'Atkinsii' is a relative giant at 20cm tall. Try a burnt-orange foxglove — Digilatis parviflora — for later colour.

How to grow

Snowdrops can take a while to establish as dry bulbs, so are best planted "in the green" (that is just after flowering, while still in full leaf). Persuade a friend to let you divide a clump, or buy them mail-order from a specialist nursery.

Replant at the same depth — up to the white stem — with some sharp sand for drainage.

Spectacular in its transformation, Miscanthus will anchor a scheme throughout the winter with its distinctive skeleton.

Usually found towering at the back of the border, Miscanthus really comes into its own in the autumn, when its feathery silver panicles unwind from its upright foliage. In shades of claret, red, purple and brown, the bold arching flowers fade through pink to silver, becoming fluffy with age. The tight clumps of narrow foliage also change colour in winter, turning orange, copper, rust and cinnamon. Spectacular in its transformation, Miscanthus will anchor a scheme throughout the winter with its distinctive skeleton.

With Dogwood: Miscanthus sinensis ‘Flamingo’ with Cornus florida ‘Rainbow’

Leaning into the russet arms of the cornus, Miscanthus adds a bit of architectural weight to the planting scheme. In late summer, you get wonderful claret-red flowers that look like wet mops (but more elegant). These Miscanthus flowers cascade from the plant, leading the eye to the dogwood below.

As the autumn colours of the dogwood intensify, the flowers of the Miscanthus fade through pink to a silvery white. The winter silhouette of the grass will remain strong throughout the winter, so combine it with spring-flowering bulbs for extended interest. Try Eranthis hyemalis, Narcissus cyclamineus and the dwarf species tulip ‘Fusilier’, all of which can be planted this autumn.

How to grow

Miscanthus grows well in any soil and autumn is one of the best times to plant them. Try to position flowering varieties so they catch the afternoon sun, and leave the flowerheads on throughout the winter so they shimmer in the low light.

Cut down to the base in late January. Miscanthus bulks up steadily, so it will need dividing every five to seven years. Divide in spring, but always take care when handling the foliage, as it is sharp and can cut your hands.
