Tink I have that happen from time to time with the big heavy double blooms...and rosea plena,Mrs.Perry Slocum, and Perry's sunset all have a huge heavy double bloom.......I don't think its a disease...just really long stems and a heavy bloom-kind of like a peony does...the blooms that do that tend to be blooms on the outer edge of the pot..the ones that grow up thru the leaves get alot of support from the leaves themselves....I've looked in my books and can't find any kind of diseases that would cause it...everything that I've read affects the leaves-not the bloom...Maybe Frank might know of something that would cause it...but, I can't find anything...
