I wanna add that the Clem I need also has to be bright in color and Long Blooming..

I don't think it is Barbara X Jackman..it is Barbara Jackman..a pruning group 2..that is on COTW if you wish to research it...Jackmanii is a pruning group 3 and a nodding purple variety whereas Barbara Jackman is large Mauvy blue color with reddish coloured stripes..I have seen Jackmanii at both Lowe's,Walmart and Home Depot...Jeanne
ps...it is thought that Barbara Jackman just might be a seedling from C. patens

Here is a link that might be useful: Clematis Barbara Jackman

I have Haku Ogon with mine but it isn't mature enough yet to really have done anything.

Jackmanii needs to be hard pruned every year, Henryi doesn't.

Rebecca clem, a new introduction this year. She is bright scarlett red, a type 2. Or try a large flowered purple clem.

Whats a good Large , Dark Purple Clem that is long blooming, vines itself ?

Apart from that how many types of Jackmanii are there? Whats the diff? How is Polish spirit diff from regular jackmanii?
