Oenothera versicolor, the red evening-primrose, is a species of flowering plant in the family Onagraceae, native to South America, from Peru and Ecuador down to Bolivia and Northern Argentina [2] This species is not as common in cultivation as other members of the genus but popular cultivars including 'Sunset Boulevard' are grown in gardens around the temperate world as the plant is hardy down to at least -10'c. [3]

Other common names include sundrops, red sundrops and orange evening-primrose.

Description

Oenothera versicolor is a bushy perennial growing to 1 m (3 ft 3 in) tall. [3] It blooms throughout summer and into early autumn. The flowers grow on spikes and are individually around 8-6cm in diameter with four petals each. The leaves are lanceolate and glossy. The reddish orange flowers appear in clusters around the top of the spike and are hermaphroditic. Unlike in some species of Oenothera, the flowers bloom during the day rather than at night although their superficial similarities to the common evening primrose still earns this species the title of evening-primrose.
