Add to My Plant List
Vine Hill Manzanita (
Arctostaphylos densiflora
) is a very rare species of manzanita, endemic to Sonoma County, 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 that is owned and protected by the California Native Plant Society.
The local habitat is mostly chaparral on sandy shale soils. This manzanita is also cultivated as a landscape plant. The species is the origin of several popular cultivars including 'Sentinel' and 'Howard McMinn.'
This is a small shrub growing in low, spreading clumps under 4 feet 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 an inch long. It bears numerous flower clusters of light to bright pink urn-shaped flowers. The fruit is a drupe about half a centimeter wide.
