I have probably grown more than 500 irises between four gardens in Virginia and one in Monterey. Now in NC I'd like to have 75+ but it will be a challenge. The most at one time - probably 100. Faves: COLETTE, CLOUD BALLET, CONCERTINA (I), VICTORIA FALLS, all the pinks are pretty. Oh yes, and the yellows and purples! If I could only have one I guess it would be HOLLYWOOD NIGHTS. Hope I never have to make that pick
