Triphysaria eriantha subsp. eriantha

Family: Orobanchaceae · Type: annual · Native

Yellow-eyed grass is a California native annual found in coastal, north coastal, central California, California Ranges, Sierra Nevada, Great Valley, Central Western, Peninsular Ranges, and Modoc Plateau bioregions in grasslands and foothill habitats at elevations below 1,600 meters. Flowering from March to May, this delicate plant produces bright yellow flowers with distinctive corolla coloration. Growing slender and low to the ground, it reaches heights of approximately 10 to 30 centimeters with thin, branching stems. Its leaves are narrow and linear, arranged alternately along the stem, contributing to its subtle grassland appearance. The tiny yellow flowers emerge in small clusters, blending softly into its grassy surroundings.
