RAH, it is also late growing... At least it as been for me. It tends to come back to life after winter longer than other species of SAV I've seen. I got it to establish in one pond I tried it in but not the other. I think it got crowded out too fast by the curly leaf pond weed in the one. The other I think I did a good enough job of cleaning it off and had no curly leaf pond weed hitch hikers. I just poked my finger in about a half inch, and then stuck the plant's root down in and then covered with bottom sediment. I planted about 15 plants in an area about 6 foot square. From looking just the other day, it has filled in nicely and began to spread. I think I have found a wild source of it as well, so I may try harvesting more this summer to move to that pond also. If it is what I think it is, I will send a few samples to Bill for proper ID.
