description_en: Genus of about 30 species of perennials from dry, rocky sites, mostly in the Mediterranean. They are vigorous, architectural plants, with striking foliage and flowers. The dark green, oblong- lance-shaped to broadly ovate, usually basal leaves, up to 90cm (36in) long, are variously lobed and toothed, sometimes spiny. The tubular, 2-lipped flowers are generally 3.5-5cm (1 1/2-2in) long, usually with spiny bracts and sepals in combinations of white, green, Yellow, pink, or purple. They are borne, some-times in ranks of 4, in erect, terminal racemes, to 1.2m (4ft) tall. Grow acanthus in a spacious border; they are also good for cutting or drying. In frost-prone areas, grow A. montanus in a cool or temperate greenhouse or conservatory.
