I was wondering the same. Glad I haven't eaten it!It's nonsense about running water and w.cress. Mine has been in a still pond for over a year and doing really well. It flowered and seeded earlier in the year and has spread up the banks (I've pulled that out).I've been trying to grow some to eat (love the stuff) in pots, but either it seems to dry out or the slugs get it. must try harder!
