Then the type of Clematis that you want are the Integrifolias...I have Clematis "Hakuree","Petite Faucon" and "Odoriba"..you can go to COTW (Clematis on the Web" and look at all the integrifolias and find just the color you want....Click on "Clematis Search" and on the type...click on "Integrifolia"....Jeanne

Here is a link that might be useful: CLEMATIS ON THE WEB

I think it also depends if you ever are going to trim your shrubs. If yes, stick with type 3's, which you trim to the ground each spring (this includes the integrifolias as Jeanne mentioned). If not, you just want to make sure you don't have a massive clematis (e.g. autumn clematis) on a small shrub!

I have Pamiat Serdtsa growing through a viburnum, and a Polish Spirit through a serviceberry. I'd basically go with easy growing types (viticellas, especially) because they will take a while to get established in a shrub's root zone, anyway, and viticellas will come through this period faster than others.

I grow Etoile Violette through my lilac. Although they don't bloom at the same time, it's a good combo because it blooms after the lilac is finished.

Etoile Violette (purple) is a group 3 clematis, so it's pruned to about the first set of lilac branches every spring. (In case you didn't already know, that is.) It's very floriferous and blooms for a long period of time, too.

Also, a couple of years ago, I layered the EV clematis by taking a few stems (still attached to the clematis) and pinning them down to the ground on the other side of the lilac. I held it in place with a rock over winter, and it rooted. (In case you didn't know about layering...) So, I've got *lots* of the EV climbing the lilac now.
