Alnus rhombifolia
Also called California alder, Mountain Alder, Rhombie Leaf Alder
White alder is a medium-sized deciduous tree of western North America, usually found along streams and in moist riparian woodland. It is grown mainly for habitat, erosion control and shade, and is not a common garden or houseplant.
Alnus rhombifolia, the white alder, is an alder tree native to western North America, from British Columbia and Washington east to western Montana, southeast to the Sierra Nevada, and south through the Peninsular Ranges and Colorado Desert oases in Southern California. It occurs in riparian zone habitats at an elevational range of 100–2,400 metres (330–7,870 ft). While not reported in northern Baja California, it has been predicted on the basis of its climatic adaptation to occur there also. Alnus rhombifolia is primarily found in the chaparral and woodlands, montane, and temperate forests ecoregions.
