 Quercus kelloggii Newberry – California black oak

This handsome oak has outstanding foliage - bristled leaves with pointed lobes that reach 4-10."

It grows far faster than other oaks and matures to reach 30-75' with irregular trunks and a majestic, broad canopy.

It is both attractive and practical, providing excellent shade and a fall show of brilliant reds, yellows and oranges.

California Black Oak is native to southwest Oregon and is also found in the Sierra Nevada ranges of California, in USDA zones 6-10.

This oak will grow on dry benches but is less drought tolerant than Quercus garryana and will benefit from regular watering in the first year especially.

Chose a sunny to partially shaded site with acidic, sandy or gravelly soil for this rare beauty.
