From creeks and rivers throughout California, the white alder rapidly grows to become a large tree, reaching to 50 ft. or more at maturity. Serrated green leaves produce an excellent canopy above the straight, silvery-gray trunk. In winter, when the leaves have fallen, the ghostly branches make a striking silhouette with dangling catkins from the branch tips. An excellent plant for creek restoration where its aggressive roots help to stabilize banks. Keep away from irrigation pipes and foundations. Needs regular moisture and sun to light shade.
