Is it in full sun?

Too much sun you think, hoov, would do it? It is in the same place it has always been for about 5 years - but in a heat & drought situation here in Temecula!

I would think it would need sun to bloom. Sounds like it gets plenty. Probably drought then.

Several years ago I tried the native Clematis. I believe it was native to the Oroville area. It grew but was never a comparable bloomer to the named varieties. I was in a cool area along the coast. Al
