Southern live oak
Quercus virginiana
An iconic evergreen oak of the southeastern coastal plain - sprawling massive trees draped with Spanish moss define the Southern landscape. Long-lived (300-500+ years in undisturbed sites) with horizontal limbs extending 80+ feet from the trunk in mature specimens. Salt-tolerant + hurricane-resistant (the canonical coastal-plain canopy tree). Like all oaks, supports hundreds of Lepidoptera species.
