piksihk, I purchased 'Mauve Majesty' from Brent and Becky's Bulbs. They only offer them for Spring shipping though and as far as I know only offer the more cold hardy ones. Hopefully someone in a the warmer zones knows of a better source than B&B.
Unfortunately the 2nd bloom stalk on my start was nipped by baby cottontails. It seems to be doing OK.
Edit: I just checked the Mauve Majesty and there are a few new bloom stalks budding.
