Alder, Mountain

MOUNTAIN ALDER  Alnus incana tenuifolia
• A tall, multi‑stemmed riparian shrub native to the Canadian Prairies, recognized for its smooth gray bark, sharply toothed leaves, and vigorous suckering habit that forms dense thickets along streams and moist slopes.
• Produces long yellow catkins in early spring that offer an important pollen source for early‑emerging insects, followed by small woody cone‑like strobiles that persist into winter and add subtle texture.
• Highly adaptable and fast‑growing, with nitrogen‑fixing roots that improve poor soils, making it valuable for restoration, erosion control, and naturalized plantings in moist to periodically dry sites.
• Full Sun to Part Shade
• Zone 2, 3–6 m Height × 2–4 m Width
