Knobcone Point Manzanita
Really handsome little selection of the rarely seen Mt. Diablo manzanita, Knobcone Point has beautiful grey blue clasping foliage and nice glossy bark in time. Very dense grower, and best in lean soils in full sun where it can maintain the handsome compact habit. We’ve yet to see these grow larger than 4′ tall and about as wide, though in the wild they grow into large upright shrubs. Named presumably for Knobcone Point in Mt. Diablo State Park, one of the only places you can catch this stunning manzanita in the wild.
