Bromus maritimus, commonly known as maritime brome or seaside brome, is a perennial grass native to coastal dunes, bluffs, and other sandy habitats along the Pacific coast of California and Oregon. It is well-adapted to saline conditions and is often found in coastal prairies and the upper edges of salt marshes. Maritime brome typically grows to a height of 1-3 feet (0.3-0.9 meters) and has a clumping growth habit. It produces slender, nodding flower spikes in late spring to early summer, with the flowers being less showy and more functional, adapted to wind pollination. The foliage is a blue-green color, contributing to its visual appeal in naturalistic plantings.

Maritime brome is valued for its ability to stabilize sandy soils and its tolerance of salt spray, making it an excellent choice for coastal restoration projects and erosion control. It is also used in wildflower meadows and naturalistic garden settings where low maintenance and drought tolerance are desired. This grass prefers full sun to light shade and is highly adaptable to various soil types, provided they are well-drained. While maritime brome is not typically plagued by serious pests or diseases, it can become invasive if conditions allow it to spread unchecked.CC BY-SA 4.0
