Alnus incana tenuifolia

Thinleaf alder, river alder and mountain alder.

We currently do not grow this plant.

Mountain Alder is small deciduous tree that grows from Tulare County in the Sierras to Alaska and into the Rocky Mountains. Mountain Alder frequents the stream banks and north slopes. If you are a fly fisherman, this is the tree you got your fly stuck in as it is the most common alder in the mountains. Why are we planting birch from Europe, maples from Japan, when we have these neat little trees all our own? syn.
