I have often seen «proliferation» on flowers and seeds growing out of hips. When I have went round of my recent crosses, I have been surprised to see a crested bud on my Harison’s Salmon x Prairie Peace cross, that made only 3 weeks ago. It is the first time I see «proliferation» on hip (see photo)! Is there someone whom has already seen this on hips? Is it a possibility that this excrescence take the place of seeds? It is really weird!
