Native to coastal margins of the southeastern United States and the Caribbean region, Borrichia frutescens (sea oxeye daisy) occurs along Atlantic and Gulf shores in salt marshes, sandy flats, back-dune swales, and mangrove edges where periodic saltwater flooding and salt spray are common. It is a long-lived, clumping subshrub that spreads slowly from a woody base and underground stems, forming low colonies that stabilize sandy or silty substrates. Flowering heads are typically 1–2 in across with bright yellow rays surrounding a dense center of yellow tubular florets; the disk florets often show coiled styles and dark anther tips, features visible at close range. Heads arise singly or in small groups on sturdy stalks through much of the warm season, and the plants withstand brief submersion and high salinity without loss of vigor. Photographed in Florida.
