Willow oak is a member of the red oak family with willow-shaped leaves. The fine foliage of the willow oak is 1 of its best ornamental features. The willow oak has excellent texture, rounded form, attractive bark and beautiful winter features. Widely used as a shade tree and for avenue plantings, the fast-growing willow oak can reach over 60 ft. H with more than a 30 ft. to 40 ft. spread. The pyramidal shape in youth gives way to a rounded canopy in middle and old age, with lower branches drooping toward the ground. The long, light green willow-like leaves create dense shade and a graceful effect turning bright yellow before they fall. It thrives in moist, well-drained, acidic soil and full sun. The willow oak will tolerate pollution and drought and is considered a trouble-free tree as long as soil pH is acidic. Willow oak has a fibrous root system and is therefore easy to transplant. It is hardy in USDA Zones 5-9 and is shipped in a #1 pot with an average tree height of 12 in. - 18 in.
