I was just looking over my seed list to see if there might be a few plants that would be happy growing in the pond.
I've had good luck with plain old canna and impatiens. The pond is surrounded by large pines and gets sun off/on during the day. The cannas bloomed beautifully and the impatiens did great planted bare-rooted in the rocks at the edge of the falls. Also tried a couple of houseplants...Peace lily and Nephthytis. They did great in the filtered sunlight and the Peace lily even bloomed!
So, what 'land' plants have you tried in your ponds?
