Robust spineflower is a California native perennial found in coastal areas of central California in sandy or gravelly habitats.

Growing with decumbent to erect branches spreading one to six decimeters in diameter, it features softly hairy stems that emerge from the plant base. Its oblanceolate leaves are 1 to 3.5 centimeters long, with blades softly hairy on both surfaces and measuring 2 to 5 millimeters wide. The flower perianth is uniquely two-colored, with a white tube and white or rose-colored oblong lobes that are often minutely toothed.
