Paeonea suffruticosa 'Zhao Fen'
There are only a handful flowering now but by this time next week it'll be overwhelming. Tree peonies are addictive. You hear stories of recent aficionados with collections numbering in the hundreds. It's at least a moderately expensive hobby since $100.00 isn't an unusually high price for one named plant. I'm reworking the locations of some of our plants as they dislike both wet feet and water on their leaves at night. I'm relocating some to drier unirrigated locations.
