Guess you must be a fair bit ahead of us up here in the great white north (aka Southern Ontario). I won't see Clematis blooms until sometime next month. But they should be nice - it is located next to my big outdoor worm bin! :-)
The clematis looks great, I bought one just like it last month, but it hasn't grown very much. Just a few new leaves so far. When you nought the plant, was it large? Mine was just in a quart pot, so I am expecting some good things next year. This is an awesome plant, I have read that it can live 70+ years.
