Common cottonwood (Salicaceae) is a large, fast-growing tree reaching over 60 feet at maturity; weedy as seedlings and root sprouts. Leaves are alternate, simple, 3 to 5 inches long, triangular, with serrated margins and flattened petioles. Fruit is a capsule with seeds surrounded by cotton-like hairs that facilitate wind and water dispersal. Tree and shrub seedlings are not well controlled by preemergence herbicides, and selective postemergence controls are not available. Hand pull seedlings when small. [TOP]
