Alnus incana ssp. rugosa

speckled alder (Alnus incana, Alnus rugosa)

A great choice for most moist to wet areas, speckled alder is a common sight by the side of many New England streams. Though its flowers are not showy, the texture of stems and leaves provide great visual interest throughout the season. This tree is a nitrogen fixer.
