RE: Emersed Growth Experiment

I didn't know you could get R. rotundifolia to grow emersed... In my
tank, when it hits the surface, it just bends over and stays underwater.
My Pennywort does the same thing. Is there a knack to growing these out
of water?

BTW, re the mangroves, just keep this in mind: in the wild these _trees_
grow 30+ feet tall. Think that'll fit in your living room? ;-) Bonsai
techniques might work. Trim them when they get too big, and prune the
roots once a year (or more--do it whenever they start getting
root-bound). If you lop off the crown occasionally, it will throw out
more side shoots and get less spindly. :-)
