A small, round-crowned tree or clump shrub, sometimes forming thickets, Gambels oak occasionally reaches 50 ft. but is usually no taller than 30 ft. Its deeply-lobed, deciduous leaves are bright green above and paler below, turning brown or sometimes red in fall. Tree with rounded crown, often in dense groves; or a thicket-forming shrub.

Gambel's Oak is the common oak of the Rocky Mountains, abundant in Grand Canyon National Park. It is closely related to White Oak (Quercus alba L.) of the eastern United States. The foliage is browsed by deer and sometimes by livestock. Wild turkeys, squirrels, and other wildlife, as well as hogs and other domestic animals eat the sweetish acorns. The wood is used mainly for fenceposts and fuel. This species is named for William Gambel (1821-49), a naturalist from Philadelphia.

Seed Collection: Best quality acorns are picked or shaken from the tree. Collect when color has changed to brown. Best if sown immediately as acorns lose viability quickly in storage. Short-term storage in moist, shaded saw dust or sand. Acorns to be sown immediately can be soaked in hot water for 15 min. to prevent weevil infestation. Stored seed should be fumigated with methyl bromide.
Commercially Avail: yes
Maintenance: Prevent complete soil dryness, May be pruned 12 mo. out of the year, Prune to maintain shape, Fertilize 3 times a year with lawn fertilizer 3:1:2 ratio
