I have irises that have 6-7 buds per stalk with great branching that put on an incredible show because their blooms do not open into other blooms. On the other hand, I have irises with 11-12 blooms per stalk that put on a miserable garden show because the blooms open into each other and it just looks terrible. Just my personal observations. Faithful annual bloom, good increase, and insect/disease resistance is most important to me. A good iris with 5-6 buds per stalk is very welcome in my garden.
