Berberis fremontii is a species of barberry known by the common name Frémont's mahonia (after John C. Frémont).
Description[edit]
Berberis fremontii is an erect evergreen shrub growing up to 4.5 meters tall. The leaves are several centimeters long and are made up of several holly-leaf-shaped leaflets, each most often 1–2.6 centimeters long and edged with spiny teeth.[2] The leaves are purplish when new, green when mature, and greenish blue when aged.
The abundant inflorescences each bear 8 to 12 bright yellow flowers, blooming in the spring.[2] Each flower is made up of nine sepals and six petals all arranged in whorls of three. The fruit is a berry up to 1.5 centimeters wide, ranging in color from yellowish to purple to nearly black.[2]
Taxonomy[edit]
Berberis fremontii was scientifically described and named by John Torrey.[1] For many years it has been part of the controversy on if parts of the Berberis genus should be classified as Mahonia.[1][3] Friedrich Karl Georg Fedde classified it as Mahonia fremontii in 1901. However, as of 2023 Plants of the World Online (POWO) classifies it as part of Berberis.[1]
Names[edit]
The plant was named in honor of John C. Frémont.[4]
Distribution and habitat[edit]
Berberis fremontii is native to mountainous regions of the US states of Arizona, Nevada, California, Colorado, New Mexico and Utah. It grows in desert grassland and pinyon-juniper woodland.[4]
Uses[edit]
The Zuni people use the crushed berries as a purple coloring for the skin and for objects employed in ceremonies.[5]
