Nasturtium is a genus of seven plant species in the family Brassicaceae, best known for the edible watercresses Nasturtium microphyllum and Nasturtium officinale. Nasturtium was previously synonymised with Rorippa, but molecular evidence supports its maintenance as a distinct genus more closely related to Cardamine than to Rorippa sensu stricto. Yellowcress is a common name for plants in this genus.
