Live Oaks and Spanish Moss: The Trees That Define This Coast

Half the photographs anyone takes in Georgetown are really photographs of two plants. Both are worth understanding.

The live oak is the tree forming those cathedral arches over the streets — massive, low-branching, with limbs that run horizontally as far out as the tree is tall. It’s called live oak because it stays green through winter, dropping its old leaves in spring as the new ones come in, which is the reverse of what most people expect from an oak.

These trees are slow, stubborn and extraordinarily tough. Their wood is dense enough that it was once prized for shipbuilding, and their root systems and flexible limbs let them survive hurricanes that take down everything around them. Many of the ones shading Georgetown’s streets were mature before the Civil War.

Spanish moss is the gray drapery hanging from them, and almost everything people assume about it is wrong.

It is not Spanish. It is not a moss. It’s a bromeliad — a relative of the pineapple — and it’s an epiphyte, meaning it grows on trees without taking anything from them. It pulls moisture and nutrients straight from the air and rain. A tree draped in Spanish moss is not being strangled; it’s being decorated.

It grows where humidity is high and winters are mild, which is precisely why it maps so neatly onto the Lowcountry. Where Spanish moss stops growing is roughly where the Lowcountry stops.

Why they matter here. The combination — enormous horizontal limbs plus hanging moss plus low coastal light — produces the specific visual character of this coast. It’s the reason a street in Georgetown doesn’t look like a street anywhere north of here.

A practical note. Spanish moss hosts chiggers. Admire it; don’t stuff it in your bag.
