Quick Update: I have started culling plants this last week. I have removed four 5 gallon buckets worth since and expect to remove at least 6 every week until their growing season tapers.
It is amazing how much muddy-looking water runs out of the roots as I pull them from the pond and throw them in the bucket...much more muddy-looking than the water directly around the plants. The roots not only absorb nutrients, but they seem to attract and hold solids.
No flowers have shown up and their size is still on the small side. I am convinced that "they" sent me dwarfs. I'm not really complaining because larger plants might be harder to corral especially if they got anywhere near 2' high. I'd still like to try the large plants, maybe next year.
