Family: Crassulaceae · Type: annual · Native

Sierra mock stonecrop is a California native annual found in southeastern North Coast Ranges, northern Coast Ranges, California Dry Forests, Sierra Nevada Foothills, central Sierra Nevada, Great Valley, and southern Coast Ranges in open, often wet sites, rock outcrops, and clay soils at elevations of 30 to 1,500 meters. Flowering from March to May, this delicate plant produces pale to bright yellow flowers that spread during blooming and become erect when forming fruit. Growing with multiple erect or spreading branches 2 to 17 centimeters tall, it forms compact clusters across rock surfaces and vernal pool margins. Its tiny leaves measure 4 to 7 millimeters long and 1 to 3 millimeters wide, creating a fine, intricate texture across the plant's structure. The fruit is small, measuring 1.2 to 2.5 millimeters long, and remains erect to ascending with occasional glandular surfaces.
