Graceful fast-growing evergreen or semi-evergreen tree from Mexico and Central America, with drooping branches and pale grey bark. Leaves resemble birch leaves and are 5-10 cm long, dark green, leathery, with toothed margins. Most leaves are retained during winter, but some leaf-shed occurs throughout the year . Looks beautiful in spring with a mixture of new light green leaves and mature dark green foliage. Minute flowers arranged in light-green, pendulous catkins to 7 cm long (male) or in short catkins (female) on same tree. Green cone-like fruit, 1.5 cm long, turning dark brown with age.
Alnus jorullensis likes a position in full sun or partial shade and prefers moist soils of any type, but tolerates drier soils although growth will be slower and may be stunted. Copes with medium frosts to about -12oC. Root system can be invasive and it is best planted away from foundations and pipes. Train to a single leader and remove lower limbs to lift the crown.
Suitable as a specimen or shade tree. Can also be pleached, used as a screen, hedge, or bank stabilisor. Useful tree to dry out wet areas.
