Tropaeolum tricolor (Tricolor Nasturtium)

Tricolor Nasturtium, Bolivian Nasturtium, Three-colored Indian Cress, Tropaeolum tricolorum


Incredibly showy, Tropaeolum tricolor (Tricolor Nasturtium) is a summer-dormant, tuberous, perennial climber with a profusion of tricolor flowers from winter to early summer. Borne singly in the leaf axils, the small yellow flowers, 1 in. long (3 cm), are adorned with a showy purple-tipped, orange-red calyx and a long red or purple spur. They create a spectacular floral display for months and contrast nicely against the soft, bright green, deeply lobed leaves. This attractive, delicate-looking but hardy climber is one of the longest flowering species of Tropaeolum. It is mostly cultivated as an ornamental.
