原生地・分布（英語）:

説明（英語）: Genus of about 35 species of deciduous trees and shrubs from all parts of the N. hemisphere, usually found on poor or wet soils. Alders have alternate, simple, toothed leaves, and bear male and female flowers in separate catkins on the same tree. The male catkins are conspicuous; the females are smaller, and after pollination develop into persistent, woody, cone-like green fruits, which turn brown in autumn. Some alders, such as A. rubra and selected forms of A. cordata, A. glutinosa, and A. incana, are grown for their ornamental foliage, and are particularly effective planted close to water. Most, however, are notable for their ability to thrive on poor, wet soils, and are widely used in land reclamation. A. cordata, A. incana, and A. rubra are fast-growing and valuable as windbreaks.

耐寒性（英語）: Fully hardy.
