About California Goldfields (Lasthenia californica) Lasthenia californica is a widespread species of flowering plant in the Asteraceae (Sunflower) family, among a number of species in the genus Lasthenia all known by the common name goldfields. This species is native to a large part of California, Oregon and surrounding areas, where it is a very common member of the flora in a number of habitat types. This is an annual herb approaching a maximum height near 40 centimeters but generally staying much smaller. The plant is quite variable in appearance across locations and climates. The leaves are hairy, somewhat linear in shape, and one to seven centimeters long. Individuals growing along the coast may have fleshy leaves. Atop the hairy stems are flower clusters of flower heads with hairy phyllaries. The head contains many yellow disc florets with a fringe of small ray florets. Large populations of this species bloom at once in the spring to produce the carpets of yellow on hillsides and in meadows that give the plant its common name. In the garden it is most often grown from seed which germinates readily.
