Bear in mind too that clematis take several years to become mature plants. Hope you've got plenty of room between those two andreatb!
Group 3 clems should always be pruned right back in late winter/early spring to encourage the new growth which carries the flowers. Group 1 and 2 clems are slightly different, needing minimal or no pruning - just tidying, so it's more important to tie in and position new growth from a young age to achieve good coverage. Always try and find out which type you have so that you can give it the best care
