Were they pretty "thick" Sass? over crowding can cut way back on the bloom, and, if they are real thick, and the leaves are left on in the fall, it could cause a sort of "mulch effect", and smother the plant (or lead to rot). I think I would dig a clump, and investigate, to see if there are any borer signs, or rotted out rhizomes. By the way, except for one, all the iris you sent are looking good, and the SDB's bloomed really well, for the first year !..Thanks Again !...Arlyn
