I have grown P. planifolia and produced viable seed without being
submerged. I had to pollenate by hand, so that may have been a
difference. I have seen this in the wild in areas that didn't look like
they were regularly submerged, of course that's sometimes hard to judge
too. I have found P. primuliflora at the edge of a small creek growing
both on the edge and even under water. The few flower scapes I observed
were old and the seed pods had already split. The flowers were quite a
few inches above water level. It was weird to see this ping growing
several inches below water level! I have never had much success with
growing these in water in my own collection, maybe I should try.
