Coreopsis maritima is native to Southern California and Baja California, in coastal California chaparral and woodlands habitats. It grows on mainland ocean bluffs and on the offshore Channel Islands.
Coreopsis maritima is a perennial that grows 10–40 cm tall but sometimes to 80 cm (4 to 32 inches). The plant has foliage that is lobed and mostly linear in shape with lobes that are 5–30 mm long and 1–2 mm wide. The 12–20 mm long flower phyllaries number 12–13, sometimes more, and they are lanceolate shaped.
Plants bloom in late winter to early summer, with normally one or two flower heads per stem, on 15 to 30 cm long peduncles, but sometimes 4 or more flowers can be found per stem. Flower heads have 16-21 ray florets typically and the laminae are 20–35+ mm long.
The disc corollas are 5.5–7 mm long.
