Description and Growing Information

General DescriptionThis self-seeding vine produces white flowers in the late summer months. It spreads vigorously and prefers sunny areas but will tolerate partially shade as well.
ShapeClimber.
LandscapeWorks well along fences, trellises or arbours where it can climb and be supported.
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.
