Winter-blooming Clematis
Clematis cirrhosa
vineWinter-blooming clematis is an evergreen vine prized for its delicate, nodding flowers that bloom from late autumn through early spring when most gardens are dormant. Native to southern Europe and North Africa, this vigorous climber produces small, bell-shaped flowers in shades of white, cream, or pale pink, often with distinctive red speckles on the interior. The finely divided foliage provides year-round interest, and the silvery seed heads extend the ornamental season.

Harvest Tips
Winter-blooming clematis is grown for ornamental flowers and foliage rather than harvest. Enjoy flowers on the vine for maximum visual impact. Cut flowers for indoor arrangements in late morning after dew dries; they have a short vase life (3-5 days) but add delicate beauty to winter bouquets. Leave seed heads on the plant for extended winter interest.
