5 essential … plants for winter interest

In the depths of winter plants which provide structure, colour and fragrance in a garden are especially welcome. Here are a few easy plants which will offer much, if not all, of that.

It isn’t just leaves and flowers that add colour to the garden – stems can do it too and those of shrubby Cornus (commonly known as ‘dogwoods’) do it in style. Depending on the variety, at this time of year their upright stems provide a stunningly vivid display of dark red, orange, limey green or dark bronze-black, from leaf fall right through the winter.

For maximum impact, go for a group planting of 3 or more and they will look truly spectacular in an open spot where they will literally light up when the winter sun hits them.

Although you could argue its star turn is in winter, Cornus alba ‘Aurea’ also produces small white flowers in spring followed by white berries in autumn and its golden yellow leaves turn red and orange in Autumn.

So basically it’s a great plant for interest pretty much all year round.  It isn’t fussy about soil, but will do best in moist soil and is a useful plant for wet areas of the garden.
Top tip: Prune hard to 30-40cm above ground in early spring to prevent the shrub getting too large and to rejuvenate it so that fresh coloured stems grow each year.

Hamamelis or ‘witch hazel’ is definitely a wonder in winter when the bare branches are covered in clusters of sweetly scented yellow, orange or red spidery flowers. Plant it on a woodland edge, or in winter border alongside a path, where its fragrance can be appreciated and you can cut the flowering twigs and bring them indoors to perfume your house in winter.

Hamamelis intermedia 'Bernstein'

This large spreading shrub/small tree grows (slowly!) up to around 4m in height and spread, so give it plenty of space to expand in time. Hamamelis prefer a moist, well-drained neutral to acid soil in sun or partial shade.

Helleborus sternii is a very attractive evergreen perennial with pretty creamy-pink-green flowers that will brighten up a winter woodland or shady border from January to March.

Standing about 30cm tall it has glossy, prickly-edged leaves and provides architectural shape in the border all year round, so it’s a great plant if you want some attractive evergreen structure at a low level or to grow under trees and shrubs.  It’s also ideal to plant in a raised flower bed, where the flowers can be seen more easily.  Helleborus sternii likes a neutral to alkaline soil in sun or partial shade and will benefit from a mulch of well rotted organic matter in autumn. Most hellebores are very hardy, but this variety may need a bit of shelter from cold winter winds.

Phyllostachys Aurea is a tall, strongly upright growing bamboo that’s great for hedging and screening, but also makes a very elegant specimen plant whose stems when mature can add a wonderful splash of golden colour to your winter garden.

Phyllostachys

For maximum impact, plant in full sun and prune the lower side shoots away to reveal the canes in all their glory.  If you’re not too keen on the yellow colour, opt instead for Phyllostachys nigra which has very attractive black shoots.  Plant in moist, well drained soil in sun or partial shade, and protect from cold, drying winds.  Top tip: if you don’t want to find this plant running amok through your garden (and the garden next door!) surround the roots with a non-perishable barrier that will restrict the plant’s spread. You have been warned!!

Mahonia x media ‘Charity’ is a tall, imposing and highly architectural plant that will add year round structure and winter interest to a shady area of the garden. Despite its large size and prickly leaves, this plant has one of the most delicious and delicate of scents, very like that of Lily of the Valley, which makes a wonderful surprise in the winter.

The spikes of fragrant pale yellow flowers are held above rosettes of large dark green, holly-like leaves from November to March and provide a valuable source of nectar for pollinating insects in winter while the blue/black berries that follow will attract birds into your garden.  This hardy shrub will be happy in a moderately fertile moist or well drained soil.

5 essential… plants for birds over winter

Winter is a hard time for garden birds.  They need to eat a lot in order to keep warm and survive the cold nights, but falling temperatures make their regular food supplies scarce.  Putting up feeders is one solution, but many garden plants double-up as life-saving food resources for garden birds and no one has to remember to fill them!  The seeds and berries of many plants provide nutrient rich snacks from late summer into winter, whilst others hide tasty insects in their stems and foliage or provide sheltered roosting spots.  Here are five of the best bird-friendly plants to include in your garden.

Ivy (Hedera helix) is one of the very best sources of both food and shelter for overwintering birds.  Its distinctive creamy white flower heads appear from October onwards and their nectar attracts insects for robins and wrens to feed on.

The large black berries which follow are devoured by a whole range of birds, including blackbirds, song thrushes and starlings while the dense foliage provides roosting spots out of cold winds and shelter for hibernating insects which make more snacks for the birds!
Gardening tips: Only mature plants over one metre in height will produce flowers and berries and ivy that’s kept tightly clipped year round won’t get a chance to flower either.  Try to keep at least a section of ivy in the garden that can get a bit messy and wait until early spring to get the shears out.

Holly, ivy’s traditional companion, is also well worth considering as part of a bird friendly garden.  Birds prefer red berried varieties such as our familiar native species, Ilex aquifolium, or English Holly, with its glossy, very prickly dark green leaves and abundance of small red berries from late autumn.  As well as feeding the birds, the berries provide a long-lasting splash of colour over winter as they ripen in late autumn, but don’t tend to be eaten until later winter.

Like all hollies, Ilex aquifolium is very slow growing, but will eventually reach 10 metres and make a very elegant architectural specimen tree for a large lawn or woodland planting.  Beware if planting in a border as the leaves will make weeding very painful!  Hollies thrive in any soil as long it is not waterlogged and tolerate pollution, winds and seaside conditions.
Gardening tips: Only female plants produce berries and require a male plant for fertilisation, so, unless you know you already have a male plant nearby, it’s safest to plant both.  It isn’t necessary for the male to be the same species so go for something contrasting, like ‘Silver Queen’ with its distinctive silvery margined leaves and purple stems.

Another all-time berrying favourite with birds is Sorbus aucuparia, otherwise known as the Mountain Ash or Rowan.  Its large bunches of deep red berries are a rich source of food for numerous species.  And if you’ve ever seen them glowing against a bright blue autumn sky, you know it isn’t just the birds who enjoy them.  This is a pretty tree in all seasons, with a naturally conical shape, dainty mid green, fern-like foliage and sprays of tiny white flowers in spring.  Berrying times vary depending on variety of tree – some starting as early as August, and others not until November.

It’s tougher than it looks and can tolerate harsh conditions while its modest height of 15m x 7m makes it ideal for a smaller garden.  Rowans prefer full sun to light shade and slightly acidic soil, but will tolerate any soil type.
Gardening tips: Rowans require minimal pruning. Remove any broken, diseased or crossing branches in late autumn or winter.

The common Hawthorn or May tree, Crataegus monogyna, supports over 300 insect species and provides food and shelter for birds all year round.  Shiny clusters of deep red berries, or haws, ripen in autumn and can stay on the tree until February or March to be enjoyed by many bird species including blackbirds, chaffinches, greenfinches, redwings and fieldfares.

It is a small, rounded, deciduous tree with spiny branches, glossy, deeply lobed leaves and flat sprays of creamy-white flowers in May.

I LOVE Hawthorn blossom – a true sign that spring has arrived, and such a pretty flower.

A lovely specimen tree for an informal or wildlife garden, hawthorn also makes an excellent hedge, either on its own or as part of a mixed wildlife hedge.  It thrives on any well-drained soil in full sun to partial shade and can tolerate exposed and coastal sites. Height and spread: 4-8m.

Rosehips are also a rich source of vitamins and antioxidants for overwintering birds. Some of the largest produced are the heavy round orange or red hips of Rosa rugosa (either ‘Alba’ or ‘Rubra’), which are especially popular with blackbirds, fieldfares and mistle thrushes. (Smaller hips are produced on Rosa canina (the Dog rose) and these last into late winter.)

rose-hips
Rosa rugosa is a vigorous species rose with distinctly pleated, leathery, dark green leaves that turn a buttery gold in autumn and a constant succession of fragrant, single, yellow-centred flowers from June to September. It makes an excellent informal hedge for an open, sunny site on fertile, humus rich, well-drained soil.

Gardening tips: Rosa rugosa requires little pruning.  Remove one third of older stems every 2 or 3 years to rejuvenate the plant.

5 essential … low growing shrubs for ground cover

Whilst we often think first of perennials when looking for ground cover plants, there are many low growing shrubs that do the job quickly and effectively and that can provide a longer season of interest and more spread for your money.

 
Cotoneasters are wonderfully versatile shrubs which can be evergreen or deciduous and vary widely in size and form.  However, one thing that they all have in common is their long season of interest and easiness to grow.  Cotoneaster conspicuus ‘Decorus’ is a low growing, semi-evergreen cotoneaster with very small, glossy dark green leaves, an arching habit and a mature height and spread of 1-1.5m x 2m.

cotoneaster-conspicuous-decorus-janet-bligh

The branches are smothered in small white flowers for a long period in summer which in autumn are followed by bright red berries.  Any well-drained soil and any aspect will suit this Cotoneaster which makes it especially useful in dry, shady spots, but it may need protection from cold, drying winds in colder areas.

Nandina domestica ‘Firepower’ provides neat, colourful ground cover with a long season of interest in a sun or part shade and looks great planted in groups.  It is a dwarf form of heavenly bamboo with a compact, rounded form and shiny mid-green leaves that turn fiery shades of red and copper in autumn.

nandina-firepower-janet-bligh

Additional autumn interest is provided by the glossy red berries while in mid-summer conical clusters of tiny white flowers appear amongst the leaves.  Frost hardy (it may need some protection in colder areas), it is not fussy about soil type as long as it is moist and well-drained.
Garden tip: lightly cut back any shoots that are spoiling the overall shape in mid to late spring.

As well as providing wonderful fast growing ground cover in full sun or partial shade, Salvia officinalis ‘Purpurascens’, or purple sage, also scores highly on good looks, aroma and usefulness.  The highly aromatic young leaves emerge a deep reddish purple maturing to a lovely soft grey/green with a mauve hue (the hotter and sunnier the conditions the deeper the purple colouring).  Purple sage combines particularly well with any purple/lilac/mauve flowered plants such as lavender or nepeta, and bees love sage’s own beautiful lilac/mauve flowers that appear over a long period during May to July.

salvia-janet-bligh

Purple sage leaves have the same culinary uses as common sage including making a tasty, astringent tea which has a variety of medicinal properties and the edible flowers look really lovely scattered over summer salads.  Sage is fully hardy as long as it is grown on well-drained soil that is not acid and it makes a good container plant.  Height and spread: 100cm x 80cm.
Garden tips: Prune plants lightly after flowering and in spring to keep them bushy.  Mature and/or leggy plants can be pruned hard in spring (when it can look a bit shabby after winter), but take some cuttings as insurance.  Sage is prone to becoming woody and is best replaced every 4-5 years.

Viburnum davidii is a good looking shrub for all seasons with a low growing, naturally domed shape that makes for great ground cover beneath other taller shrubs of more vertical habit.  The large leathery oval leaves are dark green and heavily veined and held on red tinged stems.

viburnum-davidii-janet-bligh

In May flattened heads of tubular white flowers appear, followed later in the year by startling metallic turquoise berries on bright red stems (NB: cross-pollination must occur for fruits to be produced).  A must for woodland borders, Viburnum davidii is also happy in full sun and on any moderately fertile, well-drained and moist soil.  Height and spread: 1m x 1-1.5m.
Garden tips: Little to no pruning required.  If pruning is carried out, cut back to strong stems or to plant base to retain domed shape.

It’s hard to beat a good ground cover rose for sheer floriferousness and, well, ground covering.  Rosa ‘Kent’, one of the ‘Towne and Country’ series, is a repeat-flowering, reliable performer that forms a small, neat mound and looks good over a long season.

rosa-kent-janet-bligh

Slightly scented, semi-double white flowers with a cream flush open in great abundance from July to September, set off perfectly by the shiny dark green leaves and followed in autumn by small red hips.

rosa-kent-low-shrub-janet-bligh

Requires a fertile, humus rich, moist soil and full sun to light shade.  It makes a good patio plant in a container and the flowers, which stand up well to rain, are also good for cutting.  Height and spread: 1m.
Gardening tips: Little annual pruning required.  Remove dead, diseased, damaged or congested branches to the base in late winter.  If plants grow too large for their allotted space, prune vigorous branches by one third and prune side shoots to two or three buds from main stem.

5 essential … plants for winter seedheads

Even in death plants with interesting seed heads that stand well over autumn and winter manage to look strikingly beautiful especially on those rare but magical early mornings when they are coated in hoare frost and sparkle in the sun.  Not only do they look good, but their seeds provide a valuable source of food for birds, especially in cold winters when other foods may be scarce. With all this in mind, it’s important to stop and think whether you might be depriving your garden of some winter wonder before wielding the secateurs in the autumn tidy up.

Teasel (Dipsacus fullonum) is a native British wildflower which makes a strong architectural statement in a sunny relaxed planting scheme.  In summer, spiny pale green, thistle-like flower heads rise on strong stems from prickly rosettes of leaves and from mid to late summer are covered in tiny pale lilac or white flowers.  The flowers act as a magnet for bees and the seed heads have the same effect on goldfinches whilst also looking wonderful right through the autumn and winter months.

teasels-janet-bligh

These are biennials, flowering in the second season of growth and once established they will self-seed quite prolifically so will need to be controlled by weeding out unwanted seedlings.  Teasels are not fussy about soil type and are happy in full sun or part shade.  Height and spread: 150 cm x 50cm.

A dramatic perennial that is also a valuable addition to the winter border, Phlomis russeliana provides a strong focal point from late spring to early autumn owing to its long flowering period.

phlomis-firgrove-photographic

Whorls of pale yellow flowers are produced at intervals along tall, erect stems above large heart shaped leaves and provide striking silhouettes throughout winter.

phlomis-seedheads-janet-bligh

Again, bees love the flowers so this is an ideal plant for the wildlife garden and also works well in Mediterranean or Prairie style plantings and gravel gardens.  Phlomis russeliana is a vigorous, spreading perennial that needs room to grow and will do so happily on any reasonably fertile, well-drained soil.  Height and spread: 90cm x 75cm.
Gardening tips: Shorten any frost damaged stems in mid-spring, cutting back to just above a healthy bud.  Remove any weak or diseased stems to ground level.

Fennel (Foeniculum vulgare) produces clouds of soft green, feathery foliage that smell and taste of aniseed and are delicious in salads and fish dishes.

fenneljanet-bligh

In late summer large flat umbels of sulphur yellow flowers attract hover flies and are followed by aromatic seed heads that are eaten by birds, but whose skeleton still makes an attractive and imposing presence in autumn and winter on stems up to 2m tall.

fennel-janet-bligh

Bronze fennel, which has the same characteristics but with beautiful bronze leaves, looks particularly striking grown with Verbena bonariensis which also maintains a fairly sturdy winter outline. Fennel likes a sunny position on fertile, loamy, well-drained soil, but will grow in partial shade where it produces ample foliage but fewer flowers.  Height and spread: 1.5-2m x 45cm (at the base).
Gardening tips: Self-seeds prolifically especially in very hot weather so weed out unwanted seedlings regularly.

The seed heads of biennial Honesty (Lunaria annua) are truly beautiful.  Rounded to oval in shape, the cases are dainty, paper thin and silvery translucent with the flat black seeds clearly visible inside.  The dried stems and seed heads of Honesty are much more fragile and delicate than those of the other perennials mentioned so far, but remain on the plant well into autumn and look wonderful especially when backlit by the sun.

honesty_lunaria_annua-anne-burgess-635791

White or lilac flowers in May and June precede the seed heads and are very attractive to bees and butterflies making this another good candidate for the wildlife garden.  Honesty flourishes in sun or partial shade on fertile, moist, well-drained soil where it will self-seed and naturalise happily.   Height and spread: 90cm x 30cm.
Gardening tip: Pinch out growing tips in spring to encourage bushier growth.

Many ornamental grasses provide excellent structure in autumn and winter and among these is Miscanthus sinensis ‘Yakushima Dwarf’ which makes an ideal front of border feature for winter interest.   Its short, stout tufts of green leaves with white midribs form clumps about 1m tall.  In mid to late summer fluffy pink, tassle-like flowers emerge from the centre of the clump, ageing to silver and persisting long into the winter months.  This grass makes an excellent specimen plant in a small garden and looks very effective planted in generous drifts in larger borders.  I grew it as a hedge in my last garden and it became a real feature in autumn when the low sunlight shone through the flowers.

miscanthus-yakushima-dwarf-janet-bligh

Happiest and most free flowering on an open, sunny site it will also tolerate some shade and performs well on a wide range of soils.  Height and spread when flowering about 1.5m (but if you want less spread it’s easy to hold in the centre of the plant with supports or tie with string).
Gardening tips: Cut foliage down to the base in early spring.  Large clumps can be divided in March to April.
