Anybody ever grow them in their pond before. I saw them for sale in the water garden section at a local plant store, and bought one. Everything I find online about them refers to growing them as a terrestrial plant. I'm wondering if anybody here has grow them directly in their pond before, how they did, and what sort of climate they were in?
I don't recall ever seeing them in water garden departments before.
