Trichocoronis wrightii var. wrightii (Wright's trichocoronis) is a native California perennial in the Asteraceae family, recognized by Range edge population of primarily southwestern genus; distinctive corolla coloration.
Wright's trichocoronis is a rare (CNPS 2B.1) California native perennial found in the Central Valley and southern California coastal regions, specifically in the San Jacinto Valley, inhabiting moist places and drying riverbeds at elevations below 500 meters. Flowering from May to September, this plant produces white flowers with a distinctive maroon throat in small heads approximately 5 millimeters in diameter. Growing with delicate, few-branched stems, it forms compact clusters in seasonally wet environments. Its flowers feature white corolla lobes with a unique color transition, showing white at the base and maroon toward the throat. The small fruit measures approximately 1.5 millimeters long, reflecting the plant's diminutive and subtle botanical characteristics.
