Tree Peonies in north Florida
Has anyone had any success or know of anyone having success growing tree peonies in zone 8B, north Florida around Ocala, Gainesville? How much chilling is required? What effect does the hot humid climate have on successful culture and can those conditions be overcome or blunted. I've been told the lutea hybrids are the best best, as they are grown successfuly in south China with 340 frost free days. I've read of successes in southern California by defoliating them in November to force dormancy. Just how far south in the southeast have tree peonies been grown and how important is chilling and low humidity?
