Vine Hill Manzanita
Arctostaphylos densiflora
  
About Vine Hill Manzanita (Arctostaphylos densiflora) 25 Nurseries Carry This Plant Arctostaphylos densiflora is a very rare species of manzanita known by the common name Vine Hill manzanita. It is endemic to Sonoma County, California, where it is known from only one extant population of 20 to 30 individuals. These last wild members of the species are on land near Sebastopol which is owned and protected by the California Native Plants Society. The local habitat is mostly chaparral on sandy shale soils. It is also cultivated as a landscape plant. The species is the origin of several popular cultivars including 'Sentinal' and 'Howard McMinn'. This is a small shrub growing in low, spreading clumps under a meter in height, although cultivars may get taller. The plant does not form a burl, and stems may root where they are in constant contact with soil. The shiny green leaves are oval to widely lance-shaped and less than 3 centimeters long. It bears numerous flower clusters of light to bright pink urn-shaped flowers. The fruit is a drupe about half a centimeter wide.
