説明（英語）: Genus of 5-10 species of broadly rounded to upright, dioecious, evergreen, coniferous, large shrubs or small trees found in forest extending from N. temperate areas to the Philippines and Central America. Yews are grown for their reddish-brown, frequently peeling bark, and their linear, dark green leaves, often paler beneath; these are spirally arranged but often appear 2-ranked. On the female plants, single-seeded, oblong-ovoid fruits are produced in open, fleshy arils. Grow as specimen plants or use for hedging and topiary; the prostrate forms make good ground cover, even in dense, dry shade. Most tolerate exposure, dry soils, and urban pollution. All parts (but not the arils) are highly toxic if ingested.

耐寒性（英語）: Fully hardy.

栽培（英語）:

繁殖（英語）: Sow seed as soon as ripe in containers in a cold frame, or in a seedbed; seed may take 2 or more years to germinate. Insert semi-ripe cuttings in late summer or early autumn; take cuttings from strongly upright shoots (except for prostrate cultivars), otherwise they may not form a strong leading shoot. Graft cultivars in early autumn.

病害虫（英語）: Resistant to most diseases, except Phytophthora root rot. May be damaged by tortrix moth caterpillars, vine weevil, and yew scale.
