Florida Rosemary

Ceratiola ericoides

Florida rosemary is one of the oldest, most distinctive shrubs of the Florida scrub, a relict plant community that botanists believe has persisted, largely unchanged, since ancient shoreline eras when much of the peninsula lay underwater. Its needle-thin, aromatic foliage recalls the culinary herb rosemary closely enough to have borrowed its name, but the two plants are not related, and Florida rosemary has no history of use in cooking or herbal medicine. For scrub naturalists and early Florida settlers, it served a different kind of purpose, its silvery presence a dependable sign of deep, well-drained sand and of the gopher tortoises and scrub-jays that depend on that same ground. Rather than earning a place in the medicine chest, this plant earned its keep as a quiet architect of the scrub itself, shaping the open, sandy patches that give the whole community its distinctive, wind-swept character.

Safety.

This plant has no history of use as food or medicine and should not be eaten; its foliage contains compounds that suppress competing plants and have not been shown safe to ingest. It is unrelated to culinary rosemary despite the shared name.
