My big, spectacular irises, that's who. Lots of strappy leaves, but not even a hint of a bud. Last year, oodles of blossoms -- this year, zip. I know I should have divided the clumps early in the spring and added fertilizer, or something, but the weather has been so unrelentingly dismal, for at least a full year now, that I haven't been feeling like mucking about in the soil.
See that spectacular lack of purple-blue blooms? It's the weather's fault.
