Cherokee, Fireworks, Rebecca. Zone 8...I like these anyone have an opinion?
Cherokee is also known as 'Ooh La La' and is one of the Evison 'Patio' collection, so very compact and free flowering. 'Rebecca' has a very intense color and is argued as the closest to a true red of any clem. If I had any more room in sun for clematis, this one would be on my list. Personally, I don't care very much for the barred or two-tone flowers but that's just my preference.
I've seen a mature 'Fireworks' and it was gorgeous with huge flowers. I was told it was a very large and vigorous grower as well. I bought one and it has not been vigorous for me. :(
I know nothing about the other two.
