Dwarf Birch Bog Birch

You recognize Dwarf Birch by its diminutive size (typically to 10 feet), dark brown resinous twigs, and occurrence on wet, boggy sites and alpine slopes throughout the Pacific Northwest. This native shrub colonizes streambanks, marshes, and mountain meadows where moisture is reliable.

Dwarf Birch thrives in moist to wet, acidic soils in sun to part shade (zones 3a-8b), reaching 10 feet at maturity. It grows at moderate pace and suits naturalized areas, erosion control, and wetland restoration. Tolerates shallow, rocky, clay, and poorly drained soils well. Watch for rust, canker, and wood decay; bronze birch borer, birch leafminer, and tent caterpillars attack regularly. Moose and other wildlife browse it heavily for winter food.
