Winter plants

Make the most of cold-weather gardening

Do you shut up shop in the garden from October to March? If you do, you’re missing the joy of growing some great winter plants that will warm the coldest of hearts (and days).

Here are some of my favourites. I don’t have space to grow them all, but one great place to see a sublime example of winter planting is RHS Harlow Carr, near Harrogate, North Yorkshire. Look for the best autumn garden colours here.

Winter plants
Arum italicum marmoratum and Carex grass

When choosing winter plants, positioning is everything. Plant them where you can see and smell them – near doorways, main footpaths and anywhere you sit inside and overlook the garden. Think laterally – winter interest plants are grown not just for flowers, but for berries, bark and shape.

When gardening in winter, it really helps to thickly mulch bare soil – it shows off the plants, insulates them against extreme cold and suppresses weeds.

Winter plants
Holly Silver Queen

Holly, ivy, stems, bark and conifers

Evergreen plants will provide structure during the colder months and a backdrop for other plants. Thankfully, shrubs seem to be back in fashion – or at least heading in the right direction.

I’ve not included specific hollies, conifers and ivies here, as they have a page to themselves. There’s also a page on coloured stems and bark.

Hellebores (Helleborus nigra, H. x ericsmithii, H. orientalis): The white blooms of the Christmas rose (H. nigra) contrast with its deep green foliage. Be warned – it never flowers at Christmas! H. x ericsmithii has silvery, serrated foliage and white flowers begin in midwinter, fading to rose pink. The Lenten rose (H. orientalis) blooms in shades of purple and white, often with burgundy speckles inside. Flowers January-April. Height 30cm.

Elephant’s ears (Bergenia): Leathery, big leaves colour up in the cold, followed by pink or white flowers in spring. Good varieties are Admiral and Baby Doll. Flowers January-April. Height 20-40cm.

Lords and ladies (Arum italicum marmoratum): Stunning white veined arrow-shaped leaves emerge in September-October, dying down in late spring. White spathes are followed by a spike of poisonous red berries in autumn. Height 30cm.

Violets (Viola): Ideal for informal bedding and a prolific self-seeder. Will flower throughout winter and spring if conditions are favourable. Height 20cm.

Primrose, Polyanthus (Primula): Hundreds of varieties, from simple native yellow primrose (P. vulgaris) to vivid bedding Polyanthus such as Fire Dragon. Flowers February onwards. Height 15-30cm.

Black mondo Nigrescens (Ophiopogon planiscapus): Black, grass-like plant that performs well with spring bulbs – or against the snow. Height 8cm.
