Oenothera erythrosepala

Oenothera glazioviana is a species of flowering plant in the evening primrose family known by the common names large-flowered evening-primrose[1] and redsepal evening primrose.[2]

The plant can be found in scattered locations worldwide, mostly as an introduced species, and its exact native origins are obscure. It may be a European hybrid of two North American species.

It has long been cultivated as an ornamental plant. In some locations it has become an invasive species.

Description

Oenothera glazioviana is generally a biennial herb producing an erect stem approaching 1.5 metres (4.9 ft) in maximum height. It is roughly hairy in texture, the hairs with reddish blistering or glandular bases. The crinkly leaves are up to 15 centimeters long.

The inflorescence is a showy spike of many large flowers. When in bud the long red sepals are visible. When in bloom each flower has four bright yellow petals up to 5 centimeters long which fade orange to red with age. The fruit is a lance-shaped capsule 2 or 3 centimeters long.
