Description

Island Oak is a rare and beautiful California native evergreen oak, closely related to the Coast Live Oak but with a slightly more refined appearance. It features leaves with less pronounced spines and often a grayer underside. It is ideally suited to the milder coastal climates of the Bay Area and is a excellent choice for a stately, native shade tree.

A California native endemic to the Channel Islands, adapted to mild coastal and island climates.
Similar to Coast Live Oak but often considered to have a slightly more graceful, rounded habit and leaves that are less sharply toothed.
Prefers the moderate, fog-influenced conditions of coastal zones but is also quite drought-tolerant once established.
Provides the same significant wildlife value and majestic presence as other native live oaks, perfect for larger coastal properties.
