Watercress-Nasturtium officinale

There are a lot of Mustard Family (Brassicaceae) nonnatives, and today we're going to add another one, watercress (Nasturtium officinale). Watercress grows on water, and  in fact requires it--the presence of watercress shows that the water is present year-round. Most of the year only the leaves are present, but right now it is producing some four-petaled flowers.

Watercress is a common food for ducks and deer. It can even be eaten by humans, although due to parasites, you should either disinfect it or eat the watercress you can buy at the grocery store.
