Best winter-flowering clematis
Browse our pick of the best winter-flowering clematis to grow.
Winter-flowering clematis bring cheer to the garden in the dullest months. There are several varieties, with the most common and easy to grow being varieties of Mediterranean native Clematis cirrhosa, including 'Freckles', 'Wisley Cream' and 'Jingle Bells'. These are hardy enough to grow outside in the UK in winter, and flower from November to 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 ‘Lunar Lass’. These are tender and are best suited to growing in a conservatory or greenhouse.
How to grow winter-flowering clematis
Grow Clematis cirrhosa in moist but well-drained soil in a sheltered spot in full sun. Its roots should be kept as dry as possible in winter, so plant it in the rain shadow of a wall where it will not succumb to winter wet. Tie stems into their support initially, after which they will twine themselves. Cut back after flowering.
Tender winter clematis should be grown in rich, moisture-retentive peat-free compost in pots in the conservatory or greenhouse. Prune after flowering.
