Just remember, when planting clematis together, they need to be the same pruning group or you'll end up in an impossible tangle.
Blue Angel (Blekitny Atoll) is an excellent plant. I have it on an arch behind the house. It has survived and thrived despite two exceptionally cold winters and throws up more stems each year. I love it.
Miss Bateman, on the other hand, didn't like going below -20C for so long and hasn't survived. Flore Pleno is thinking about it after a late start this spring following all the frosts and snow. With a bit of TLC she should be fine.
If you like blues, have a look at Crystal Fountain - very blousy but tough and is doing well here as are Multi Blue and Perle d'Azur along with pinks and purples - Princess Diana, Sunset, Little Nell, Etoile Violette, Westerplatte, Hendryetta, Nelly Moser and several more.
