Q: I have a six foot high wood fence and I want to cover it with something. It gets both sun and shade.
A: Evergreen clematis, Clematis armandii, would fill the bill. It tolerates sun as well as shade. The vine blooms in late March with white, lightly vanilla-scented flowers. A yearly shearing after flowering will keep it looking its best. Avalanche(tm) clematis has deeply cut, leathery, green leaves.
