Does anyone have
It is supposed to be able to live in a pond.
I don't have it / haven't grown it.
From what I see on the web, it can be planted in average-moisture soil (especially with a little shade), planted as a marginal in moist soil, or covered by shallow (about an inch or less) water in a pond.
I have pushed the envelope alot of times with different plants. I have a couple of shelfs in my larger pond to put my water loving plants from the yard and house. It adds intrest to the pond.
