Alnus rhombifolia

California White Alder, White Alder

There are about 30 species and many cultivars of the short-lived Alder. Most of these deciduous trees like colder climates and moist or wet soils along streams and ponds. Use in grove plantings or as single, multi-trunked trees. Spring flowers are followed by toothed leaves and cone-like fruits. Roots can be shallow and invasive. They grow rapidly in infertile and poorly drained soils. Prune in winter to remove dead or damaged limbs.
