GREEN ALDER Alnus viridis crispa
• A hardy, fast‑growing, multi‑stemmed shrub native to the Canadian Prairies, recognized for its smooth greenish bark, rounded serrated leaves, and upright, thicket‑forming habit.
• Produces dangling yellow catkins in early spring that provide an important pollen source for early‑emerging insects, followed by small cone‑like strobiles that persist into winter.
• Exceptionally adaptable, thriving in poor or disturbed soils thanks to its nitrogen‑fixing root nodules, making it valuable for reclamation, erosion control, and naturalized plantings.
• Full Sun to Part Shade
• Zone 2, 2–4 m Height × 2–3 m Width
