Camissoniopsis pallida subsp. hallii
Family: Onagraceae · Type: annual · Native
Hall's evening-primrose is a California native annual found on northern slopes of the Santa Barbara Mountains, southern Mojave Desert, and northern Sonoran Desert in desert slopes, flats, and washes from creosote-bush scrub to pinyon and juniper woodland at elevations of 30 to 1,800 meters. Flowering from March to August, this delicate plant produces pale yellow flowers with petals 6.5 to 13 millimeters long. Growing with slender stems up to 30 centimeters tall, it spreads in loose, open formations across arid landscapes. Its leaves are typically narrow and elongated, arranged alternately along the stem, adapting to the harsh desert environment. The plant's small hypanthium and delicate sepals contribute to its subtle, ephemeral beauty characteristic of desert wildflowers.
