distribution_en:

description_en: Genus, now including Cheiranthus, of about 80 species of annuals, biennials, and mainly evergreen perennials, often woody based, found mostly on well-drained, calcareous soil from Europe to N. Africa, W. and C. Asia, and N. America. They are cultivated for their often yellow flowers, to 2.5cm (1in) across, each with 4 petals arranged in a cross, borne in dense, usually elongating, corymb-like racemes. Most wallflowers produce inversely lance-shaped, toothed, softly hairy leaves, 3-12cm (1 1/4-5in) long. Many are ideal for a rock garden or wall, the front of a sunny border, or a raised bed. The biennials are popular as spring bedding plants or in a border.

hardiness_en: Fully hardy to frost hardy.

cultivation_en:

propagation_en: Sow seed of perennials in containers in a cold frame in spring. Take nodal or heeled softwood cuttings from shrubby perennials in spring or summer. Sow seed of biennials in a seedbed from late spring to early summer, grow on in a nursery bed, and transplant to flowering positions in mid-autumn. Provide cloche protection where frosts are severe or prolonged.

pests_en: Susceptible to fungal and bacterial diseases including clubroot, mildew, leaf spot, root rot, and mosaic virus. May suffer damage from slugs, snails, and flea beetles.
