Family: Alliaceae · Type: Herb · Native
Allium praecox (Early onion) is a native California herb in the Alliaceae family, recognized by low elevation, shaded habitat, flowers becoming papery in fruit.
Early onion is a California native perennial found in southwestern California (excluding Santa Barbara and San Bernardino regions) on shaded, grassy slopes at elevations below 800 meters. Flowering from March to May, this plant produces pale pink flowers in clusters of 5 to 40 blooms, with blossoms 8 to 12 millimeters long. Growing with slender stems 20 to 60 centimeters tall, it develops 2 to 3 widely channeled or flat leaves that are about half to three-quarters the height of the stem. Its distinctive bulb is ovoid to nearly spherical, 10 to 18 millimeters wide, with an intriguing outer coating featuring a subtle, wavy herringbone pattern of transversely elongated cells. The perianth parts are somewhat spreading to erect, turning a dull purple when in fruit and folding over the seed capsule.
