Watercress or yellowcress is an aquatic plant species with the botanical name Nasturtium officinale. Watercress ("Nasturtium Officinale") is a rapidly growing aquatic or semi aquatic perennial plant. Nasturtium, marigold, and "Cassia" buds have sometimes been used as a substitute. Gluconasturtiin is named from its occurrence in watercress ("Nasturtium officinale"). Nasturtium was sired by Watercress out of the mare Margerique. It is home to numerous threatened or endangered species, including Gambel's watercress ("Nasturtium gambellii"). In addition, watercress "Nasturtium officinale" increased after the 1993 flood event. "Rorippa" formerly included several species of watercress, now placed in the genus "Nasturtium". It is not closely related to the genus "Nasturtium" (which includes watercress). These include kikuyu grass, bracken, blackberry, nasturtium, Taylorina and arum lily. Common names for this plant include nasturtium tree, parasol leaf tree and bingabing. Though not related, the leaves of the garden nasturtium also have a peppery taste. Other records include "Nasturtium officinale", "Tovaria pendula" and "Tropaeolum moritzianum". Wreath nasturtium ("Tropaeolum polyphyllum") is a prostrate plant originating from Argentina and Chile. Individual names of patterns included "Nasturtium", a leafy, summery design.
