Description en: Genus of about 300 species of annuals, mostly rhizomatous and stoloniferous perennials, and a few evergreen shrubs, widely distributed in a range of habitats, including mountains, dry, rocky hills, scrub, wasteland, meadows, forest clearings, and streamsides, especially in N. temperate regions. The leaves on the square stems are short-stalked or stalkless, opposite, and become progressively smaller up the stems; basal leaves are lance-shaped or elliptic to ovate, entire to scalloped or toothed, wrinkled, prominently veined, hairy and stalked. Many species are aromatic, occasionally unpleasantly so. The tubular, 2-lipped, often hooded, usually white, yellow, pink, red, or purple flowers are borne in racemes or spikes of axillary whorls. Most are attractive to bees and butterflies. Grow taller perennials in a mixed or herbaceous border. S. byzantina is ideal as edging or as ground cover. Low-growing, hairy-leaved species, such as S. candida, S. citrina, and S. lavandulifolia, are suitable for a dry bank, gravel garden, raised bed, or rock garden, but need protection from excessive winter wet; they are best grown in an alpine house. Grow S. sylvatica in a wild garden.

Hardiness en: Fully hardy to frost hardy.

Cultivation en:

Propagation en: Sow seed in containers in a cold frame in autumn or spring. Divide or remove rooted sections of perennials in spring as growth begins. Take greenwood cuttings of shrubs and subshrubs in early summer.

Pests en: Slugs may be a problem. S. byzantina, in particular, is susceptible to powdery mildew.
