Santa catalina popcornflower is a California native annual found in southern San Joaquin Valley, southern Coast Ranges, Channel Islands, and Mojave Desert in grasslands, coastal scrub, and desert scrub at elevations generally below 1,400 meters. Flowering from April to June, this plant produces small white flowers that emerge in delicate clusters. Growing with prostrate to ascending reddish stems that reach variable heights, it has distinctive coloration with red-tinted lower stems and leaf margins.
