Absolute Treasure is my favorite, but I have only been growing it one season, so who knows?
Colors are fairly accurate in this photo, but it can be paler too.
A newly planted rhizome pushed out a huge bloom stalk and still managed 3 very good increases in a spot where some of its neighbors had partial rots during winter. The mother rhizome has given me 2 more increases this summer and this is despite of me moving the whole clump (without trimming the fans)to a prime location in the middle of the worst drought I ever experienced during the sunniest summer on record here in Sweden.
So a bit early to tell perhaps, but I do love this iris a lot.
