For many, winter is the season where we forget about the garden mainly because we tidy it in the autumn and put it to bed until spring, but it needn’t be so. A well planned winter garden can be just as striking as your spring and summer show, raising the spirits even when the weather doesn’t.
Winter Interest from Flower, Leaf and Stem
Winter flowering plants are less abundant than those that bloom in the summer, but they offer a lot. Exquisite colour and form are often complemented by amazing scent, an evolutionary race to attract the sparse pollinators at this time of year.
Hamamelis or Witch Hazel are medium to large shrubs or small trees with delicate and spiderlike flowers in fiery tones of red, orange or yellow. Borne on bare branches after the attractive autumn foliage has fallen the flowers are highly fragranced. Underplant with hellebores whose glossy green foliage sets off beautiful single or double blooms. The Hamamelis niger and x ericsmithii varieties flower before Christmas and are usually white, while the orientalis types flower later but offer different shades such as reds, pinks, purples, yellows and even slate grey. Other great options for underplanting include hardy cyclamen, winter aconites and of course snowdrops. Galanthus nivalis is the common snowdrop but there are many varieties to choose from the plants that flower in winter in the UK.
The fine stand alone shrub Mahonia japonica has leathery spine toothed evergreen leaves which often colour up in autumn and shows winter flowers. The flowers are usually yellow, although some varieties orange and are held in clustered racemes above rosettes of foliage. As a bonus, small purple fruit follow, extending the season of interest.
For a smaller space or to clip into a low hedge Sarcococca confusa, or ‘Christmas box’ is a fine choice. The glossy evergreen foliage stays mid green all year round and the stems are graced by masses of tiny white fragrant flowers in December. Plant near a path to get the benefit of the glorious scent.
Chaenomeles and Jasmine nudiflorum
If you are planting against a wall or trellis try planting Chaenomeles (or ornamental quince) for masses of flower power or Jasmine nudiflorum (winter jasmine) for a reminder of the golden sunshine of summer.
For stem colour it is hard to beat the dogwoods. Varieties of Cornus alba, sericea and sanguinea have bright winter stems in shades from yellow, lime-green, orange and red to purple-black. Plant in groups of three or five for massed stem effect and cut back to 6 to 12 inches from the ground each spring to ensure the brightest stem colour the following winter.
Creating Striking Winter Plant Contrasts
In the world famous Winter Garden at the Sir Harold Hillier Gardens in Romsey, one of the most striking plant pairings is the bone white stems of Rubus cockburnianus, or white stemmed bramble, arching over massed plantings of Ophiopogon planiscapus ‘Nigrescens’.
If you prefer more colour in your garden, pair the orange stems of Cornus sanguinea ‘Midwinter Fire’ with low evergreens such as Euonymus fortunei varieties or evergreen ferns. Summer grasses such as molinia, panicum and pennisetum often hold their seed heads long into the winter and contrast well with evergreen plants such as Viburnum tinus in bud and flower at this time of year.
Plants For Winter and All Year Round Interest
In a sheltered spot, an acer (Japanese maple) is a great winter plant. Many have bright winter stems almost as impressive as cornus. They are hardy in most UK winters, however once established these may need protection in colder months. Acer ‘Sango-kaku’ has red-orange stems while the ‘Katsura’ is bright yellow and ‘Beni-maiko’ scarlet.
Skimmia offer all year round evergreen foliage which is glossy green and attractive. They set bud in late summer and hold it throughout the autumn before flowering in late winter or early spring with a fragrant, ‘lily-of-the-valley’ scent. The flower heads are actually made up of hundreds of tiny individual flowers. There are male and female varieties. Females such as Skimmia ‘Nymans’ will produce red berries if pollinated by a male such as the Rubella which tend to have showier flowers. There are also self fertile varieties such as Skimmia ‘Temptation’ with attractive flowers and berries together on the same plant. Skimmia look great planted alongside the dark winter stems of Cornus alba ‘Kesselringii’ or the bright red of Cornus alba ‘Sibirica’ and they do benefit from a little shade as too much sun can yellow the leaves.
Finally, one of the best all year round plants for the small garden is Prunus ‘Kojo-no-mai’. Look out for it in the early spring in full flower but plant it at least as much for the autumn foliage colour and the fantastic, architectural twisted stems of winter.
