Latin Name:  Alnus rhombifolia
Common Name:  White alder
Family:  Betulaceae
Author:  Nutt.

Known Hazards:  The freshly harvested inner bark is emetic but is alright once it has been dried[172].

Mature Height:  12   Mature Width:

Habitat:  Usually found in rocky or gravelly soils along the sides of streams, in canyon bottomlands and gulches, from near sea level to 2400 metres[60, 229].

Propagation Notes: Seed - best sown in a cold frame as soon as it is ripe and only just covered[200]. Spring sown seed should also germinate successfully so long as it is not covered[200, K]. The seed should germinate in the spring as the weather warms up. When large enough to handle, prick the seedlings out into individual pots. If growth is sufficient, it is possible to plant them out into their permanent positions in the summer, otherwise keep them in pots outdoors and plant them out in the spring. If you have sufficient quantity of seed, it can be sown thinly in an outdoor seed bed in the spring[78]. The seedlings can either be planted out into their permanent positions in the autumn/winter, or they can be allowed to grow on in the seed bed for a further season before planting them. Cuttings of mature wood, taken as soon as the leaves fall in autumn, outdoors in sandy soil.
