Iris blooms committed suicide!
I have several clumps of an old lavender iris. They were full of bloom stalks and suddenly nearly every one of them became limp and fell over in an upside down U shape. Some of the flowers on the lower part of the stem are OK. The stem goes on to shrivel and the flower dies. Only one or two stalks per clump are not affected. Nothing has been sprayed or put anywhere near them. We have had a lot of rain. I noticed this last year too, but only a few stems were affected. I'm ready to compost the whole bunch of them. I have many other iris, but none are afflicted in this way. Anyone seen this before? sis
