The plant was completely healthy in Zone 10a Encino, CA. NO fungal diseases at all. The foliage was gorgeous and it grew vigorously. It flowered repeatedly, but any time the direct sun hit those petals, they fried like Comtesse du Cayla's and anything descended from Agalia (I'm looking at YOU Leonie Lamesch). I liked the plants, including Purpurea's, but not being able to enjoy flowers from them due to their inability to withstand the intensity of the sun was the deal breaker. I sent it, and them, on to other homes where they could be provided conditions and positions more suitable to their fragile petals. It likely would have flowered more "continuously" had the heat and water retention of that crumbling ancient sea floor hill could provide, but there was usually evidence of fried flower clusters on the plant.
