Your Water Horseradish (Watercress) Armoracia aquatica is a
great water plant, too.

That must be what I have. Can't remember why my Dr. mentioned eating it,
but I pick off a sprigs, and OMG! Peppery, harsh taste. ~ jan

"Harsh"??? That's pretty mild for our table :-) I confess to never having
checked what species I had, but from your description I'd have to guess it
was really Water Horseradish. I wondered why it tasted _nothing_ like I
remember from childhood, when I had European Watercress (though in those
days I hated anything green, so I just assumed I remembered poorly). I
have none at my new home. I should see if it'll grow in still water.
