Are there evergreen oak trees?
Evergreen Oak trees retain their leaves year round or lose them briefly when they put on new growth. In March, the Texas Escarpment Live Oak (quercus fusiformis) drops it's leaves. The new leaves form rapidly in less than a month on average. With some of the evergreen Oaks, new leaves are brightly colored, sometimes yellow/orange as it is with the Emory Oak.

This Oak can be found growing in lower grassland elevations in climates that are hot and dry with summer monsoon rains. It can be found throughout Arizona, New Mexico and West Texas. The mature trees can be over 20 feet tall with a wide canopy. In years when acorns are produced they usually ripen in late July through August.
