説明（英語）: Genus of 200 or more species of usually spiny, deciduous, sometimes semi-evergreen trees and shrubs occurring in woodland and scrub in N. temperate regions. The leaves are alternate, simple or lobed, mostly ovate or obovate, and mid- to dark green; some species produce good autumn colour. The white to deep pink flowers are usually shallowly cup-shaped and mostly borne in flat or rounded corymbs at the ends of short, leafy shoots although, rarely, they may be solitary. Fruits, produced in autumn, consist of fleshy exteriors with bony nutlets; they are mostly red but may also be black, yellow, or bluish green. Hawthorns are valued for their long season of interest and their extreme hardiness. They are particularly useful specimen trees for a town, coastal, or exposed garden. C. laevigata and C. monogyna are also used for hedging. The seeds may cause mild stomach upset if ingested.

耐寒性（英語）: Fully hardy.
