California Goldfields
lasthenia californica
California Goldfields (Lasthenia californica) is a cheerful, low-growing annual wildflower native to the open grasslands, coastal bluffs, and vernal pool margins of western North America. During early spring, these resilient plants carpet entire hillsides and valleys in a dazzling blanket of bright, golden-yellow blooms. This spectacular display is not only a visual marvel but also a vital ecological event, signaling the peak of spring and drawing in a multitude of native pollinators. Extremely adaptable, the species often thrives in poor, clay-heavy, or serpentine soils where other plants struggle. Its rapid life cycle allows it to germinate, bloom, set seed, and die back before the harsh, dry summer heat sets in, making it a master of drought avoidance.
生息地: Found in open, sunny habitats including grasslands, oak woodlands, coastal scrub, vernal pools, and areas with clay or serpentine soils.
外見
California Goldfields are small, slender annual herbs growing up to 10 to 40 cm tall. They feature hairy, reddish-green stems holding narrow, opposite linear leaves that are sometimes deeply lobed. The plant is topped by small, daisy-like flower heads, roughly 1 to 2 cm in diameter, composed of both bright yellow ray florets and matching yellow central disk florets. Each flower head is cradled by a cup of green bracts. When growing in mass, they create dense, vibrant yellow carpets that are easily recognizable from a distance.

おもしろい事実
During massive spring 'superblooms', California Goldfields can grow so densely that their bright yellow sheets of color are visible from orbiting satellites.
Indigenous Californian peoples, such as the Miwok, historically harvested the tiny, abundant seeds of this plant to grind into a nutritious food meal called pinole.
The genus name Lasthenia is named after Lasthenia of Mantinea, an ancient Greek woman who dressed as a man in order to study philosophy under Plato.
