I almost bought it once but decided against it. It grows like other Strelitzia except its leafless. And much more expensive. I have S. reginea planted out in my yard, it grows well, but doesn;t flower because its just too wet here. It they get too much water, they don't seem to feel the need to bloom. They don;t seem to mind the wet heat, although in their native South Africa they get a little more dry heat. When I lived in California, they grew everywhere. Almost every yard always had one, and in full bloom seemingly 24/7. Here, NO ONE plants them even though they are cheap and readily available.
I almost bought the juncea from Gardino's years ago but decided no because it was a splurge and I knew even in the greenhouse where I can control water better it would get too much water
