Planted this iris from a bareroot division in early spring, it is now October 23rd and I have one bloom open and three more buds. It is very beautiful and vibrant purple and white in the fall garden. Slight fragrance. I love multicolored blooms, but to see this iris bloom in the fall, the first year.... I am very impressed. I have several reblooming TB's and look forward to my spring show! ~Brooke
