Chorizanthe corrugata

Wrinkled spineflower

Family: Polygonaceae · Type: perennial · Native

Wrinkled spineflower is a California native perennial found in the southwestern California bioregion in sandy or gravelly habitats at elevations of 70 to 1,000 meters. Flowering from February to May, this plant produces white flowers in small, delicate clusters with curved, hooked awns. Growing with compact, nearly erect stems 3 to 15 centimeters tall, it has branches ascending from the plant base, sometimes with one branch more prominent. Its leaves are mostly basal, with small ovate to round blades 5 to 15 millimeters long, covered in a thin, soft tomentose texture. The plant forms small, open clusters of three-angled involucres with spreading lobes, giving it a distinctive architectural structure in sandy landscapes.
