About La Purissima Manzanita (Arctostaphylos purissima) Arctostaphylos purissima is a rare species in the Ericaceae (Heath) family known by the common names La Purisima Manzanita or Lompoc Manzanita. It is endemic to a very small portion of western Santa Barbara County, California, near the City of Lompoc, site of Mission La Pursima Concepcion. Due to its limited distribution it is included on CNPS list 1B.1. It is a plant of the coastal chaparral on sandstone soils. This is a shrub reaching at least a meter in height and known to exceed four meters tall. It varies in shape from low and spreading to tall and erect. It is coated in long, white bristles and a dense foliage of shiny, hairless green leaves. Each leaf is round to oval in shape and smooth along the edges, and up to 2.5 centimeters long. The inflorescence is a hanging cluster of spherical to urn-shaped flowers each about half a centimeter long. It has a notably long flowering season. The fruit is a hairless drupe between one half and one centimeter wide. This is one of several Manzanita species that are unique to the central coast and it would make a nice addition to any coastal garden. Horticultural varieties known as 'Vandenberg' and 'Petite Margarita' are available that offer an especially compact shape.
