Hello,
I'm new to this forum. I'm in sePA. Z6. Need a rose & clematis to grow together in this pillar. Gets sun till noon.

Need contrasting colors, the background is a white wall.

I'm also ok with a double clematis...

How is Comtesse de bouchaud... which flowers in abundance.
With...
Venosa Violacea?

I would love suggestions that bloom longer.

THANKS...

Hi, Kris. Welcome to the forum. I once wrote a short article for this site on these pairings.

And here's a thread from the Clematis Forum with some good suggestions.
