Nasturtium

nasturtium, (Tropaeolum majus), also called Indian cress, annual plant of the family Tropaeolaceae, cultivated as an ornamental for its attractive leaves and flowers. The plant is native to the Andes Mountains of South America and is considered an invasive species in a few areas outside its native range. The peppery-tasting leaves and flowers are edible and can be used in salads or as a floral garnish. The young flower buds and fruit are sometimes used as seasoning. Unrelated, the genus Nasturtium consists of aquatic herbs of the family Brassicaceae (see watercress).
