About Allium serra McNeal & Ownbey
Allium serra is a species of wild onion native to California, and it goes by several common names: jeweled onion, pom-pon onion, and serrated onion. This plant prefers hard, rocky clay soils, including serpentine soil. It grows in the Coast Ranges of central and northern California, occurring from Merced County to Humboldt County. Each Allium serra plant grows a small herringbone-patterned bulb that averages one centimeter in diameter. It produces a long stem that holds a tightly clustered umbel of flowers. The flowers are an attractive bright pink, shaped like thimbles or bells. Fresh flowers are often iridescent, and they turn papery as they dry.
