About La Panza Manzanita (Arctostaphylos pilosula) La Panza Manzanita (Arctostaphylos pilosula) is a rare native shrub in the Ericaceae (Heath) family that grows in the Central Coast region, primarily in San Luis Obispo County. Due to its restricted range it is included on CNPS list 1B.2. It tends to grow in sandstone outcrops, at elevations from sea level to 1,300 feet. As with other species from this region, La Panza Manzanita is exposed to a very mild climate with some summer moisture provided by fog drip.
