They are very hungry, greedy plants - one of the very few for which I actually buy a specific feed. Everything else gets pelleted chicken manure, but clematis get proper clematis feed. They need cool feet, and warm heads, plenty of air to freely flow around them. Plenty of moisture when there is dryer weather. Some clematis are big strong growers, such as the montanas, and some are small, delicate little things. Some don't climb and make lovely herbaceous plants. There are nearly as many clematis as there are days in the week. Something will grow well for you, but you may have to experiment a bit.
All the best with them, they are so well worth the effort.
