Gambel oak is a large, sprawling, native deciduous shrub or small tree. It often occurs in dense thickets of strong, twisted branches and is often found in the foothills west of Colorado Springs. 

The shiny green leaves have three to five deep, irregular lobes. Although the flowers in spring are not noticeable, it produces acorns later in the summer. The grey bark is deeply grooved. In fall, its leaves turn yellow to reddish-brown. 

Gambel oak is a very drought tolerant species that is important to local wildlife.

This shrub grows naturally in the foothills areas of Colorado Springs. It is a very drought-resistant, hardy, low maintenance shrub; a good choice if the space is available for it to grow.

Stands may need to be thinned and pruned to reduce fire danger on landscapes. Prune out dead, damaged, or diseased branches as necessary.
