Gardeners' Notes:

This is my first and only clematis so far. Got it because of the long bloom time. It blooms beautifully for about a month, and then stops. Wondering if I need to amend the soil some how? Too much nitrogen? Any help appreciated. But at the end of the day - it is healthy, problem free, and gorgeous - so thumbs up!!

I agree, it is slow to start, but worth the wait. My flowers are more purple than the picture, but fabulous. I purchased extremely small bareroot plants last year and they didn't really take off until this year.
