I have a 5 inch or so start of U.nelumbifolia available for trade. It does not have a fully developed photosynthetic stolon, but has two that are starting off strong, but still juvenile. I love this plant, so I'm happy to get more growing out there. I can't figure out how to post a pic of it, but I'd be happy to email it.
I am looking mostly for:
VFT (other than typical varieties)
PM me if interested, even if you don't have anything on this list... I'd be happy to see what we can work out!
