A hybrid between Clematis paniculata and Clematis marmoraria-both evergreen species native to New Zealand.

This beautiful vine is equally content climbing on a wall or rambling along the garden floor. |
| Lore | In its homeland of New Zealand, this plants ancestor, C. marmoraria is an evergreen rock hugging crevice plant with little resemblance to the resulting cultivar. |
