Native to many shady moist spots from Santa Cruz and Yosemite north to B.C.. One of our customers report a grove in the Santa Barbara Area. One of the early Spanish expeditions along the coast in 1543 said the Indians in Santa Barbara had abundant quanities of Hazelnuts and it was part of their diet. I've seen in 2 sites to date. The first was around Ben Lomond next to a seasonal stream. It was in a narrow opening in a Douglas fir forest(full shade). Companion plants were Acer macro.and Umbellaria calif.. The duff was 2" deep and the soil was an old sand dune with a shallow hard pan with a pH of @5.5. The other site was in the Sierra Nevada at about 4000' in granitic soils. In was on a stream bank in part-shade and moist. pH was @6. The area was predominately Quercus wis., Ceanothus cuneatus,Arctostaphylos viscida, and Rhamnus calif., the companion plants were Cornus nuttallii, Aesculus calif. and Acer macrophyllum. Sawyer, et.al. in Barbour & Major lists the companion on a site on Siskiyou Mt. at the Oregon/Calif. border: Pseudo. menziesii, Chamaecyparis law.,Polystichum munitum, Acer circinatum,Gaultheria shallon, Berberis nervosa, and Acer macrophyllum.
