(Cheiranthus cheiri), an ornamental plant of the genus Cheiranthus. A blue-gray subshrub with large, yellow flowers that are gathered in racemose inflorescences, it grows in rich lime soils in southern Greece and on the Aegean Islands. Wallflowers are often forced as potted plants or as cut flowers; they also grow in open ground as biennials. Garden forms and varieties of wallflower are included in two groups: bushy forms, with several flower-bearing shoots; and single-shoot forms, without branches. These forms are also distinguished by height, the size and structure of the flower (single and double), and the color of the petals (yellow, orange, velvety brown, violet, or mottled).
