Summary
California goldfields is a cheerful annual wildflower that carpets fields with brilliant yellow blooms during spring across parts of the southwestern United States. Beyond its ornamental beauty, it has a modest but genuine history as a food plant. The Cahuilla people of southern California harvested its tiny dry fruits (cypselae), grinding them into flour for food. Although each individual plant produces only a small quantity, vast colonies can make harvesting worthwhile. The plant's abundance, ease of processing, and mild flavour make it one of the more interesting small-seeded members of the sunflower family.
Physical Characteristics

Lasthenia glabrata is a ANNUAL growing to 0.4 m (1ft 4in) by 0.3 m (1ft) at a fast rate.
See above for USDA hardiness. It is hardy to UK zone 8. The flowers are pollinated by Bees, Insects.
It is noted for attracting wildlife.
Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil.

Edible Uses:
California goldfields demonstrates that even tiny annual wildflowers can provide useful food resources. Although harvesting enough cypselae requires patience, the ease of processing, pleasant flavour, and abundance of flowering colonies make this species a worthwhile traditional grain plant. While it cannot compete with cultivated cereals in productivity, it remains an interesting and historically significant wild food of the American Southwest [2-3]. The edible portion consists of the cypselae, the dry, seed-like fruits typical of the sunflower family. Unlike many species, the entire cypsela is used rather than attempting to extract the tiny seed inside. After removing the loosely attached scales, the cypselae can be ground directly into flour. Their small size makes separating the actual seeds impractical and unnecessary. Although yields from individual plants are low, large flowering colonies can provide worthwhile harvests when timed correctly [2-3]. Edibility Rating: 3 out of 5 – A useful traditional grain plant with pleasant flavor and straightforward processing, although collecting sufficient quantities is time-consuming [2-3]. Taste and Preparation: California goldfield cypselae have a mild, pleasant flavor reminiscent of sunflower seeds with a subtle nutty character. Their texture is fine and slightly bran-like, making them well suited for grinding into flour. The fruits require very little processing. After the loose pappus scales are removed, the whole cypselae can be ground and incorporated into breads, cakes, or porridge. Their mild flavor allows them to blend easily with other wild or cultivated flours [2-3]. Seasonality (Phenology): Plants flower from February to June, with the fruits maturing from April through August, most commonly during late spring. Harvest timing is important. Mature cypselae disperse soon after ripening, and plants growing in full sun often mature earlier than those in shaded locations. Waiting until the plants have naturally dried usually produces the best-quality harvest, although slightly immature plants can be dried after collection if necessary [2-3]. Nutritional Value: No detailed nutritional analyses have been published specifically for California goldfields. Like many members of the sunflower family, the cypselae likely provide carbohydrates, small amounts of protein and oil, dietary fiber, and minerals [2-3]. Traditional Uses: The Cahuilla Indians of southern California traditionally gathered the cypselae and ground them into flour for food. A closely related species, yellowray goldfields (Lasthenia glabrata), was harvested and prepared in the same manner. Both species were known by the Cahuilla name "aklakul." No significant toxicity has been reported for the cypselae or seeds when properly identified. As with any wild seed crop, harvest only from clean sites free of herbicides, pesticides, or roadside contamination [2-3].

Other Uses
Widely cultivated as a native wildflower for meadows, pollinator gardens, and naturalised landscapes. The flowers provide nectar and pollen for a variety of beneficial insects, while the seeds may be consumed by small birds. Dense spring colonies also offer temporary habitat for many invertebrates.

Cultivation details
California goldfields grows best in full sun on well-drained soils, including sandy, gravelly, and seasonally moist sites. It readily colonizes open ground and benefits from winter rainfall followed by warm spring temperatures. Habitat: Open grasslands, fields, valleys, roadsides, open woodland, and disturbed ground from California east to New Mexico, generally below 1,500 m (4,900 ft) elevation. USDA Hardiness Zones: Zones 7–10 (grown as a winter or spring annual). Growth Rate: Fast. Plants germinate during the cool season, flower in spring, produce seed rapidly, and complete their life cycle within a single growing season. Mature Size: Typically 5–40 cm (2–16 in.) tall with a spread of 10–30 cm (4–12 in.), often forming dense colorful colonies. Cultivation: California goldfields is easy to grow from seed and is widely cultivated as a native wildflower for meadows, pollinator gardens, and naturalized landscapes. It prefers full sun and relatively low-fertility soils and readily self-seeds where conditions remain suitable. Pollinators: The bright yellow flower heads attract numerous native bees, hoverflies, butterflies, and other small pollinating insects throughout the flowering season. Identification: California goldfields is recognized by its bright yellow daisy-like flower heads, opposite narrow leaves, and small annual habit. The cup-shaped involucre with a single row of hairy phyllaries and the tiny linear cypselae bearing short awns or awn-tipped scales help distinguish it from related species. Similar Species: Yellowray goldfields (Lasthenia glabrata) closely resembles California goldfields and has also been used as food. It differs by producing cypselae that lack awns, scales, and other pappus structures, making them even easier to process.
