"It grows on well-drained soils from alkaline to slightly acid, although it is rare in the heavy clay of the true Blackland Prairies. It is thicket-forming, spreading from root sprouts to form "mottes." Escarpment Live Oak is more drought- and cold-tolerant than Coastal Live Oak (Q. virginiana), and can grow in more alkaline soil. In large portions of Central Texas, the live oak populations are hybrids between Q. fusiformis and Q. virginiana. Both species are susceptible to the oak wilt fungus."

Trees like full sun and produce green catkins in the spring. This species often retains its leaves, requires litle moisture and tolerates high temperatures.

It will grow in most soils and is hardy in USDA Hardiness Zone: 7.

The tree get its scientific name from the mature acorn/fruit, which has a very fusiform apex (fusiform means distinctly narrowed).

Acorns turn brown as they mature.
