I planted about 20 plants two years ago, and I probably have a few thousand. However it is overrun with chara which is thriving. Where there isn't chara, the plants are doing well, but stunted due to my high alkalinity. I planted about 50 full-sized non-corkscrew plants, and these can poke out above the chara, and seemingly doing a lot better. The first being aquarium store purchased, and the second being harvested from local lakes.
