Description and Growing Information
| Propagation | Root softwood cuttings in spring or semi-ripe cuttings in early summer. |
| Cultivation | Well drained soil in full sun to partial shade. |
| Pests | Wilt, powdery mildew, rust, fungal spots, and stem cankers are common. Scale insects, whiteflies, earwigs, and aphids can occur. Clematis 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 Description | Single lantern-like purple blooms. |
