Tropaeolum incisum is a perennial nasturtium from the dry eastern Andes of Argentina and Chile, grown for its yellow, peach and orange flowers and blue-grey, deeply cut leaves. It needs free-draining soil, full sun and a dry rest period, so it suits an alpine house or bulb frame more than an ordinary border.

About
Tropaeolum incisum is a species of nasturtium, with flaring petals in shades of yellow and peach, when still in bud and on the outside darker, more orange-brown and sometimes stained purple, with creeping or climbing stems, in the wild up to about 60 cm long with deeply divided, blue-grey leaves, with undulating lobes, that grows on the dry eastern side of the southern Andes mountains.
How to grow it
Tropaeolum incisum is sometimes grown as an ornamental and is on offer from several seed companies and nurseries. It can best be grown in free draining soil in full sunlight and avoiding competition, such as in a bulb frame or alpine house, particularly in climates that are moist during the plant's hibernation period.
Where it grows
Tropaeolum incisum is concentrated in the Argentinean lake district of northern Patagonia (northern Chubut, western Río Negro, Neuquén, and southern Mendoza Provinces), and can also be found in neighboring Chile but only near the passes. It may grow at elevations up to 3000 m. It grows in arid, sandy fields and low scree in the rain shadow of the Andes. Hyposchila galactodice, a butterfly belonging to the Pieridae that occurs in western Patagonia, Argentina, is a specialist feeding on Tropaeolum incisum.
