原生地・分布（英語）:

説明（英語）: Genus of 10 species of deciduous forest trees, widely distributed in temperate regions of the N. hemisphere, valued for their foliage and autumn colour. They have alternate, usually ovate to elliptic-oblong, coarsely to finely toothed, mid-or dark green leaves, and usually smooth grey bark. The monoecious flowers appear with the leaves, the males in spherical heads, the females in pairs within 4-lobed bracts, which develop into smooth or spiny, 4-segmented cupules containing the nuts. Grow in a woodland garden or as specimen trees. Use F. sylvatica for hedging or pleaching.

耐寒性（英語）: Fully hardy but, except for F. sylvatica, they require long, warm summers to thrive.

繁殖（英語）: Sow seed in a seedbed in autumn, or, after winter stratification, in spring. Graft cultivars in midwinter.
