Description and Growing Information

General DescriptionA beautiful climbing clematis that bears elegant lavender-blue bell-shaped flowers.
CultivationMedium to wet soil with full sun to partial shade.
PestsClematis wilt is caused by the fungus Phoma clematidina with the symptoms evident through wilting leaves, leaf stalks turning black and then with the stems starting to quickly wilt. There are no chemical controls available to treat Clematis Wilt. If an infection is apparent, cut the wilted stems back to the healthy tissue. Tools used should be disinfected thoroughly and removed infected tissue should be destroyed to prevent any further soil or plant infection.
Flower DescriptionLavender-blue bell-shaped flowers with curly edges. Flowers hand downward from the stem.
