About Del Norte Manzanita (Arctostaphylos nortensis) Arctostaphylos nortensis, common name Del Norte manzanita, is a shrub narrowly endemic to the mountains along the Oregon/California state line. It has been reported from only 3 counties: Del Norte County, California; and Curry and Josephine Counties in Oregon. The plant grows in chaparral and open forests at elevations of 400-600 m (1,300-2,000 ft). Arctostaphylos nortensis is a shrub up to 5 m (16 ft) tall, bearing racemes of white flowers. It is distinguished from other species in the region by the long hairs on its twigs, flowers and fruits.
