原生地・分布（英語）:

説明（英語）: Genus of about 65 species of deciduous, rarely evergreen trees usually found in woodland, mainly in Europe, Asia, and North America. The leaves are opposite and pinnate, light to dark green, and 5-50cm (2-20in) long. The flowers are borne in terminal or axillary panicles or racemes, from spring to early summer. Ashes are grown for their habit and foliage. Most have inconspicuous, petalless flowers, although some species, including F. ornus and F. sieboldiana, are grown for their ornamental flowers. F. americana; F. pennsylvanica and F. uhdei usually produce male and female flowers on separate plants; both are needed to produce the single-seeded, winged fruits. Ashes are excellent specimen trees for woodland or coastal gardens. Grow non-fruiting cultivars in areas with long periods of over 24°C (75°F), where self-sown seedlings can cause problems. Contact with lichens on the bark may aggravate skin allergies.

耐寒性（英語）: Fully hardy to frost hardy.

栽培（英語）:

繁殖（英語）: Stratify seed over winter, or chill for 2-3 months in a refrigerator before sowing. Sow seed in autumn or spring in containers in an open frame. Graft cultivars in spring on to seedling stock of the same species.

病害虫（英語）: Generally trouble free, although susceptible to a range of pests and diseases in the USA.
