The live oak is a popular evergreen tree known for its full, dense canopy, and its consistent height and shape. The cathedral live oak, a popular cultivar variety, is an ideal shade tree for many North Texas landscapes. It has small, dark green leaves that only shed to make room for new foliage and growth. Being easy to care for, this extremely drought and heat tolerant tree can adapt to nearly any soil type, making it the number one choice for any residence. This tree will reach a height of about 40 to 50 feet at maturity, growing around 1 to 2 feet annually.
