The vitcella group ae smaller flowering, but do so profusely. I use them in all sorts of places, and they are not susceptible to wilt - it seems to be the large flowered hybrids that get this. For spring (whatever that may be), the montana group are good if you have space for them, as they do get very large aned heay - gorgeous though. You can grow vitcellas through them when they have stopped flowering themselves, looks good. If you really want the large flowering clematis (and I still try with them) you need to plant them very deep indeed, then if wilt strikes they will often shoot again from the part that is underground - worth trying.
The non-climbing herbaceous clematis are good too, in pots, hanging baskets or just clambering around other things in a flower bed - mostly purples yet, but there will come more colours I am sure.
Bought a 'red' clematis this year, it isn't, it is very lovely but definitely purple, although the label shows a clear red - thought it unlikely at the time.
