Erysimum × cheiri
Also called Aegean wallflower
Wallflower is a fragrant spring-flowering perennial, usually grown as a biennial, from south-east Europe and the Aegean, with many cultivars in yellow, orange, red, purple and cream. Sow one year to flower the next, as plants turn leggy and prone to clubroot in their second year.
Erysimum cheiri, syn. Cheiranthus cheiri, the wallflower, is a species of flowering plant in the family Brassicaceae (Cruciferae), native to Greece, but widespread as an introduced species elsewhere. It is also treated as a hybrid under the name Erysimum × cheiri. It is widely cultivated as a garden plant.
This is a popular ornamental plant, widely cultivated for its abundant, fragrant flowers in spring. Many cultivars have been developed, in shades of yellow, orange, red, maroon, purple, brown, white and cream. It associates well in bedding schemes with other spring flowers such as tulips and forget-me-nots. It is usually grown as a biennial, sown one year to flower the next, and then discarded. This is partly because of its tendency to grow spindly and leggy during its second year, but more importantly its susceptibility to infections such as clubroot.
The wallflower is a garden refugee and originally native to south-east Europe, especially in the Mediterranean basin, where it grows in the wild in rock corridors. In Central Europe, it is now a wild and naturalized archaeophyte, which occurs mainly in warmer areas, but is only scattered for the time being.
