This clematis tends to bloom heavily for me during the spring.

Planted 3 years ago. First two winters it got chopped down by somebody (bunnies I believe). But, always came back nicely. Last winter I protected the wood from the bunnies and this spring I'm getting a spectacular show. Packed with blooms!

I planted an asao in 2004 it didn't do much of anything the first year.It got one large bloom in the spring of 2005. I than cut it back to about 6 inches . It took off after that and reached about 10 to 15 feet or better and has about 20 flower buds on it right now 7/29/05. I am really excited about its second bloom...should be awsome..

This cultivar, for me, seems to be prone to the clematis condition that makes the older stems die to the ground. It is vigorous in producing new ones, however, and it is a prolific bloomer. Reliably blooms from late April through mid May.
