So I looked outside today now that the snow has cleared and I realized that one of my roses actually set a lot of hips last year that I hadn't noticed - now, all guides seem to suggest harvesting at a much earlier time than now, but I figure that storing them in the fridge for several months is supposed to replicate wintering over. Are the hips going to be bad since they've been sitting on the bush, or would there still be some chance of getting viable seedlings out of them?
