A handsome and popular shade tree, Quercus phellos (Willow Oak) is a medium to large, deciduous tree with a straight trunk and an oval to rounded crown with upswept branches. It is noted for its long, fine-textured, willow-like leaves, up to 5 in. long (12 cm). Bright green in summer, the foliage turns yellow or russet in the fall. The gray to dark brown bark is smooth when young, becoming rough and fissured with maturity. The nearly round acorns, 1/2 in. long (1 cm), with thin, saucer-like cap, are striated with brown and black bands. They are a valuable source of food for many species of mammals and birds. A fast grower, Willow Oak tolerates urban conditions very well and is appreciated as a street tree, shade tree in lawns, in reclamation sites, and in rain gardens. It is also incredibly tolerant of heat, drought, and stress once established. Long-lived (200 years), it is excellent for wildlife.
