Description

Alnus serrulata is a suckering medium-sized deciduous shrub. It typically forms dense 12' height thickets, but can be trimmed up to form small trees of 20' or more. Flowers are in the form of showy catkins that emerge before the leaves. It produces showy, cone-like fruit that persist well into winter. Foliage turns yellow to orange in fall.

Cultivation

Hazel alder is a moisture loving shrub, often used as a wetland restoration species. It does well with wet feet, and regular inundation in up to 3" of water. Can be grown in drier yet moist conditions, but will need to be placed under filtered light, protected from direct sun. Individual plants are short lived, but form self-regenerating colonies by means of root suckers. Blooms in early spring; March, April. Zones 4-8

Propagation

Propagate from seed, or by cuttings.

Additional Notes

The roots have the ability to fix nitrogen, making it a good plant to rehabilitated depleted soils. It provides valuable food and shelter to a host of wetland birds and small mammals.
