Tropaeolum /trəˈpiːələm, troʊ-/, commonly known as
nasturtium (/nəˈstɜːrʃəm, næ-/; literally "nose-twister" or "nose-tweaker"), is a genus of roughly 80 species of annual and perennial herbaceous flowering plants. It was named by Carl Linnaeus in his book
Species Plantarum, and is the only genus in the family
Tropaeolaceae. The nasturtiums received their common name because they produce an oil similar to that of watercress (
Nasturtium officinale).
