It's time to trim and I have to cut back a lot of Rotala rotundifolia. I'm not entirely sure how much it will be but at a minimum it will be 15 stems ~8" long, probably more. I'm looking for some good ground cover and would like to try my hand at some Hemianthus callitrichoides. Let me know if you have some you are willing to part with. I'm not set on this though, so if you have something else offer it up.
