Noteworthy Characteristics:
Live oak is a large, long-lived, evergreen oak that typically grows 40-80?tall with a short trunk, low branching and a broad-spreading rounded crown. It is native to coastal plains and woods from Virginia to southern Florida and Texas. This is a majestic tree whose massive spreading limbs and branches are often seen draped with Spanish moss in many parts of its range. Live oaks were planted along many old southern plantation roads and over time have become a symbol of the South. Insignificant monoecious yellowish-green flowers in separate male and female catkins appear in spring. Fruits are ellipsoidal acorns (to 1?long), with scaly cups that extend to approximately 1/3 the acorn length. Acorns are valued food for a variety of wildlife. Elliptic to obovate, leathery, shiny dark green leaves (to 5?long) have smooth edges. Leaves are evergreen. Wood makes excellent fuel because of its high density. Live oak acorns mature in one season.
Problems:
In its native range, live oak is generally considered to be a long-lived, low-maintenance tree. Root rot may attack coastal trees. Oak wilt is a serious problem in some areas. Insect galls may damage foliage appearance.
Uses:
A shade tree for large lawns or parks.
