| | Propagating Isoetes spp.
Isoetes spp. are ones of my all time favorite plants: pretty, versatile, and noninvasive. The last attribute is becoming increasingly negative however. I would like more of this plant; but short of splitting the modified stem (corm-like structure), I don't know how to go about propagating it. I've tried planting the individual quills without success.
Has anyone managed to propagate this plant through some OTHER method(s) than the division of the corm-like structure?
