Himalayan firethorn is a naturalized shrub found in San Francisco Bay and San Bernardino Mountains on canyon slopes and disturbed ground at elevations below 500 meters. Flowering from February to June, this plant produces white flowers in clusters with multiple blossoms.

The fruit is a bright red berry approximately 5 to 8 millimeters wide, providing attractive ornamental value.
