Phragmipedium Grande in the South Californian outdoor?
I've have looked up that Phrag like grande can handle very bright light almost to those of cattleya, but I wonder if they can handle low humidity aswell? Socal temperature can have warm night in the summer, and it never frost in winter but the humidity where I am can best be at 50-60% on the average summer days.
As for winter, I'll probably might have to bring them in as it can only get around 10-20% this time.
I bought a Phrag. Grande by mistake instead of the Phrag. Humboldtii, I really wanted the long hanging stringy bloom of the slipper flowers. But knowing that the Grande is a hybrid I think I have a chance with it outdoor.
I'd keep an eye on it in the winter. Kovachii, besseae manage just fine in the cold, but some of the long-petaled species and their hybrids may be less productive after sustained weeks on (very) chilly nights. I used to keep them outside year round but after switching them to the greenhouse, I've had better results. Just my experience!
