Winter-flowering clematis bring cheer to the garden in the dullest months. There are several varieties, with some of the most common and easy to grow being varieties of Mediterranean native Clematis cirrhosa, which includes 'Freckles', 'Wisley Cream' and 'Jingle Bells'. These are hardy enough to grow outside in the UK during winter and flower at some point between November and February. These evergreen climbers can be grown through other plants, such as climbing or rambling roses, where they extend the season of colour and interest, flowering when the rose is dormant.
Other winter clematis include Clematis napaulensis and Clematis urophylla 'Winter Beauty', which are only borderline hardy so need a reliably mild spot.
How to grow winter-flowering clematis
Grow Clematis cirrhosa in moist but free-draining soil in a sheltered spot in full sun. Its roots should be kept as dry as possible in winter, so make sure the soil does not hold water for too long, adding compost or grit if necessary, as this will help to avoid the roots rotting during long periods of cold, wet weather. Tie stems into their support initially, after which they will twine themselves. Cut back lightly after flowering.
Borderline-hardy winter clematis must be planted somewhere mild, and in colder parts of the country may only be viable in a conservatory or greenhouse. Prune lightly after flowering.
