DistributionThis species is strictly coastal in its state range, occurring in nearly all counties that border the Atlantic as well as a few that border Pamlico Sound.

This is one of the few woody plants that are restricted to coastal habitats over its range. It is found north to the Delmarva Peninsula and occurs around the Gulf Coast to southern TX. It does occur in some inland counties in TX.
AbundanceCommon and generally easily found along most of the coast, north to Dare County.
HabitatThis is a species of salt and strongly brackish marshes, typically along the drier edges of them, where it can grow in a monoculture zone there, often mixed in with another shrub in the Composite family – Iva frutescens.
PhenologyIt blooms and fruits over long periods, from May to September.
IdentificationThis is a unique shrub in the Carolinas, being the only Borrichia in the country; one other occurs in the West Indies. It is a tardily deciduous shrub that grows only to about 2 feet tall, in dense stands. It is often unbranched, and it has very thick and fleshy oblanceolate leaves that grow to 2-2.5 inches long. The leaves tend to be very pale, glaucous gray-green. At the top of each stem is a single large yellow flower with many rays that spread to 1-2 inches from ray tip to tip. Even without the flower it should be easily identified; Iva frutescens has a wider branching pattern and its leaves are thinner, are longer, and are more lanceolate in shape.
