Preferred Scientific Name; Tropaeolum majus Preferred Common Name; common nasturtium Taxonomic Tree; Domain: Eukaryota Kingdom: Plantae Phylum: Spermatophyta Subphylum: Angiospermae Class: Dicotyledonae [30][31], Tropaeolum was previously placed in the family Tropaeolaceae along with two other genera, Magallana Cav. It has leaves with five to seven lobes and small, long-spurred, red and yellow flowers. Advertisement The flowers and leaves can be eaten in salads and the immature seeds pickled and used like capers. Title Mansfeld's Database of Agricultural and Horticultural Plants The monotypic genus Magallana was characterised by having winged fruit, and the two species of Trophaeastrum lacked spurs.

[32], "The Plant List", a collaboration between the Missouri Botanical Garden and the Royal Botanic Gardens, Kew includes the following accepted names of Tropaeolum species names.

This naturalized ornamental and edible garden plant is native to Brazil and Peru. A molecular study undertaken in 2000 found Tropaeolum to be paraphyletic when the other two genera are segregated, so Magallana and Trophaeastrum were reduced to synonyms of Tropaeolum. Tropaeolum majus is a PERENNIAL CLIMBER growing to 3.5 m (11ft) by 1.5 m (5ft) at a fast rate. It was named by Carl Linnaeus in his book Species Plantarum, and is the only genus in the family Tropaeolaceae.
