Description
Chrysolepis sempervirens grows as a shrub, typically shorter than 3 meters high.[5] The bark is gray or brown in color and smooth.[4] In July and August, the shrub produces a green catkin, or spike-like inflorescence, which fruits as a yellowish bur, 20-60 mm thick, densely spiny, and containing one to three light brown nuts.[4][5] The abaxial side of the young leaf is golden, while the adaxial side is green,[5] and the evergreen leaves remain on the plant throughout the year.[6] Rounded leaf tips distinguish C. sempervirens from C. chrysophylla, the only other species in this genus, which grows in more coastal habitats.[7] There are no subspecies or varieties of C. sempervirens.[3]
Ecology
Chrysolepis sempervirens is generally more shade-tolerant than C. chrysophylla, and can therefore grow in the lower strata of coniferous forests.[3] The shrub is pollinated by the wind,[8] and its fruit ripens in the second year of development.[9] The nuts are a good source of food for birds and rodents, which help to further disseminate the seeds.[9]
Uses
The nuts are edible, though small, and taste similar to hazelnut. Indigenous peoples of California gathered and roasted them as a food source.[10] Today the species is occasionally grown as an ornamental shrub in native plant gardens, valued for its dense form, attractive foliage, and adaptation to dry, rocky sites.[6]
