I've been wondering whether I should add a separate forum for questions. I see you have yours incorporated in Clematis Discussion, which seems right, because it probably will be the forum with the heaviest traffic.
What about an ID forum? Theoretically, people now can go down the list of cultivars and choose the thumbnail that's most applicable, but we all know that clems can look quite different in different gardens and in different seasons, and the thumbnail might not match.
One of my clems is already starting to bloom, by the way -- c. Armandii. As soon as it gets more showy, I'll come over and post some photos of it.
