need help choosing
I would love to have a clematis on an arch I have in my back yard. I've tried climbing roses but am losing them to severe black spot. I put in a clematis once, and it didn't come back the second year, and I'm pretty sure that it just didn't get enough sun. It was Jackmanii. That's why I tried roses. While researching some resolve for the black spot, I came across some info on clematis that might be somewhat shade tolerant. The arch is in a spot that is totally shaded until midday, then gets strong sun until it moves behind a large maple tree growing over the yard next door, probably for about 3 hours. Once that happens, it gets dappled sun for another 1 1/2-2 hours at most. Is that enough?
