説明（英語）: Genus of about 50 species of perennials, some dioecious, widely distributed in the N. hemisphere in sunny, rocky habitats. They have thick, fleshy rhizomes producing scaly brown basal leaves, and stiffly erect, unbranched or occasionally branched stems that bear alternate, triangular-ovate to lance-shaped, often toothed, fleshy, grey-green stem leaves. The small, star-shaped, green, yellow, orange, or red flowers, with 8-10 prominent stamens, are borne in dense, rounded, terminal, corymb- or raceme-like heads, and may be unisexual or bisexual. Rhodiolas are cultivated for their foliage and flowers, and are suitable for a rock garden, or the front of a mixed or herbaceous border.
