Erysimum cheiri is a species of herbaceous, perennial flowering subshrub in the family Brassicaceae native to southern Europe but widespread as an introduced species elsewhere. In New Zealand it is grown as a ornamental plant but it has escaped and now grows wild. It can tolerate maritime exposure and hence wild plants can be found in coastal conditions.
Erysimum cheiri has one or more highly branching stems reaching heights of 15–80 cm. The leaves are a bright green and are generally narrow and pointed and may be up to 20 cm long.
During summer the top of the stems have club-shaped inflorescences of fragrant 4-petaled flowers. The flowers have purplish-green sepals and rounded petals which are two to three centimeters long. They are mostly bright yellow or yellow-orange to brown, but sometimes appear reddish purple to burgundy. The flowers fall away to leave hairy, narrow pendant, dehiscent seed pods (siliques) that are several centimeters long.
