Ok, its been a warm and wet spring so far, and for a while, from the way they were laying, I thought the rain or neighbor kids were breaking the flower stems and knocking them to the ground. However, the kid angle is seeming doubtful and I've now found them flopped over even when it hasn't rained. Anyone have any ideas what might be causing this? The ones that seem to flop over the most are the ones where they are the thickest. Might this be the key?
