The live oak is a popular evergreen tree known for its full, dense canopy. The Southern live oak, though similar to the cathedral live oak, is particularly iconic of the southern south. 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 North Texas residence. The southern live oak is known for living hundreds of years, where many large and old specimens can still be found in the deep southern United States. This tree will reach a height of about 40 to 50 feet at maturity, growing around 1 to 2 feet annually.
