The best clematis in my garden started as plugs - they seem to establish so much better than the bigger plants from a GC. So next year you should be pleased with them, and the following year you will hopefully be amazed
The larger ones might have flowers already, but they will have been hurried along in conditions which are nothing like your garden. Plugs get to grow into their surroundings.
