説明(英語): Genus of about 600 species of monoecious, deciduous, semi-evergreen or evergreen trees and shrubs, widely distributed in woodland and scrub in the N. hemisphere, and grown for their habit and foliage. They have usually fissured bark, downy to hairless shoots, and alternate, entire, lobed, or toothed leaves, which in some deciduous species give excellent autumn colour. The tiny male and female flowers are produced separately on the same plant in late spring and early summer; the males are borne in pendent catkins, the females singly, in pairs, or in racemes, followed by usually ovoid brown nuts (acorns) in scalY cups. The acorns are mostly 1-3cm (1/2-1 1/4in) long, sometimes more, and solitary or paired, but in some species are borne in racemes. Oak trees are best as specimens in a large garden or a park.
耐寒性(英語): Fully hardy to frost hardy.
栽培(英語):
繁殖(英語): Sow seed in containers in a cold frame or seedbed as soon as ripe. Graft in mid-autumn or late winter.
