Also be sure to edit your member page to show what state you're in so we can better aid you. Stop by local aquarium and pond shops as well. It's often sold as a pond plant.

I have some seeds you can have, but you must really promise not to give them to anyone living in warmer climes. I grow them in a raised bed with lots of water and they thrive (keep cutting as you use it) until the first frost. A zip code "general delivery" will probably get it to you,though you will have to let the PO know , and you may have to pick it up there.

Sorry, after all this ... I was on Page 3 of this forum and found out that it is illegal to send these seeds across state lines. The season here is not long enough for them to go to seed, but with climate change, who knows...?
