Dunno. I've had pretty good luck with L. repens, even in straight gravel
(CO2 injection, high light). My bad luck with Ludwigia seems to be stem
rot, which I could never correlate with anything tangible, other than my
clipping it. Sometimes the cutting would root immediately; sometimes the
bottom 2" would rot away and roots would form above that. Usually the
mother plant would do OK. It likes high light very much, responding with
beautiful big leaves (ok, I guess most plants do this). I ONCE got them
to flower at the water surface, though who would notice.. they're little
cancerous-looking nodules at the stem.
Finally a plug... anyone in Seattle on this list, come to the auction
tonight. I'm bringing in lots of plant cuttings. :)
