Frémont’s Pincushion, also known as Desert Pincushion
Chaenactis fremontii
Family: Asteraceae, commonly referred to as the aster, daisy, composite, or sunflower family
Fun Facts
Chaenactis fremontii is often the most abundant spring wildflower in the lower Mojave and northern Sonoran deserts, where it is a significant food source for desert tortoises (Gopherus agassizii Cooper). It also extends seaward into the southern San Joaquin Valley area of west-central California, often as hybrids with other taxa.
Habitat
Chaenactis fremontii is native to California, Arizona, Nevada, Southern Utah, and Mexico (Baja California). The plant is often found in washes, alluvial fans, hillsides, and sandy or gravelly locations.
