Salix laevigata (Red willow) is a native California tree in the Salicaceae family, recognized by 5 stamens and tree form distinctive.

Red willow is a California native tree found in riverbanks, seepage areas, and lakeshores across California's central and coastal regions at elevations below 1,700 meters. Flowering from December to June, this tree produces delicate catkins with yellow or white flowers. Growing up to 20 meters tall with brittle branches, it features distinctive yellow- or red-brown twigs that become increasingly smooth with age. Its leaves are strap-shaped to lanceolate, measuring 53 to 190 millimeters long, with finely crenate edges and dense white or rusty-white undersides. The tree's young branches are notably hairy, with leaf petioles featuring small glands and leaves that range from white-hairy to glabrous with time.
