Common Goldenstar

Bloomeria (bloo-MER-ee-ah)

Family: Asparagaceae Native

Golden Stars is a genus of small, flowering, corm-forming, herbaceous perennials in the Asparagaceae family with three varieties native to California and the Baja Peninsula. In nature, the plants are typically found in dry flats, hillsides, chaparral, coastal sage scrub, valley grasslands, and oak woodlands, often in heavy soil. The genus is named after Hiram Green Bloomer (1819–1874), an early San Francisco botanist. Golden Stars grow best in well-drained, moist, sandy or loamy soil and full to part sun, although the plant does not tolerate full shade. It does require consistent moisture during the growth season, but when the foliage dies down in the fall, it should be kept dry. Golden Stars produce corms, which can be harvested to propagate plants the following year. To grow from the corms, store them in a cool, dry space until spring. Plant by covering the corm in 3 inches of soil. Golden Stars are not cold hardy and will be injured at temperatures below 25 degrees F (-4 degrees C). A wildflower in California. Plant it in large groupings for a good showing. Diseases, Insect Pests, and Other Plant Problems: No known diseases or insect pests.
