原生地・分布（英語）: N.temp., rare S.America, Afr.

説明（英語）: Genus of about 45 species of mainly deciduous shrubs and small trees, and a few woody-based perennials, from grass-land, thickets, woodland, rocky slopes, and swamps, mostly in N. temperate areas. The usually opposite, sometimes alternate leaves are lance-shaped-ovate to broadly ovate, and mid- to dark green. Small, star-shaped flowers are borne in terminal cymes, with or without bracts, in dense umbels with yellowish bracts that fall as the flowers open, or in dense clusters with conspicuous white or pink bracts. Those borne in cymes or umbels are followed by loose clusters of berries; those borne in clusters are followed by tight terminal clusters of berries or have the clusters united into compound, fleshy, strawberry-like fruits. Dogwoods are grown for their showy bracts, elegant habit, fruits, and colourful autumn leaves; some are effective specimen trees or shrubs, especially in a woodland garden. Those with colourful winter shoots, grown as pollards, are useful for many situations, from a shrub border to a waterside garden. Use C. canadensis in woodland or for ground cover in a shrub border. The fruits of some species may cause mild stomach upset if ingested; contact with the leaf hairs may irritate skin.

耐寒性（英語）: Fully hardy to frost hardy.

栽培（英語）:

繁殖（英語）: Sow seed in a seedbed in autumn, or stratify and sow in spring. Divide C. canadensis in spring or autumn. Graft variegated cultivars of C. alternifolia and C. controversa in winter. Root greenwood cuttings in summer. Take hardwood cuttings of those grown for winter stems in autumn.

病害虫（英語）: May be affected by anthracnose.
