Camissonia campestris subsp. obispoensis

San Luis Obispo evening primrose is a California native annual found in the southern Coast Ranges in marine deposits within openings of chaparral and oak woodland at elevations of 100 to 500 meters. Flowering from March to May, this plant produces yellow flowers with delicate, bright petals in small clusters. Growing with generally decumbent stems reaching 10 to 30 centimeters long, it spreads low across the ground. Its leaves are narrowly elliptic with coarse serrated edges, creating a distinctive textured appearance. The small yellow blooms emerge close to the ground, creating a subtle carpet of color across coastal grassland openings.
