原生地・分布（英語）:

説明（英語）: Genus of about 14 species of tufted, low-growing, usually rhizomatous perennials, mainly from woodland in W. and C. North America. They have radical, heart-shaped, kidney-shaped, or pinnatifid leaves. Unbranched, leafy, upright stems produce narrow, upright, spike-like racemes of small, tubular to bell-shaped, violet to blue, or rarely pink or white flowers, mainly in spring. Grow in a woodland or rock garden, or at the front of a shady, herbaceous border. Grow S. pinnatifida var. lanuginosa in a scree bed or alpine house; it is hard to grow and flower buds often abort.

耐寒性（英語）: Fully hardy, but intolerant of winter wet.

栽培（英語）:

繁殖（英語）: Sow seed in containers in an open frame in autumn. Divide in early spring as growth begins.

病害虫（英語）: Prone to attack by slugs and snails. Aphids and red spider mites may damage S. pinnatifida var. lanuginosa under glass.
