Last updated
Quercus sadleriana (Fagaceae) is a low, evergreen shrub native to the Klamath Mountains of southwestern Oregon and northwestern California. It grows only about 6 feet tall, making it the smallest oak in its range. The chestnut-like leaves are distinctive for an oak.
Sadler oak inhabits cool, moist, high-elevation sites on north-facing slopes. It is rare in the nursery trade but occasionally grown by native plant enthusiasts. The species' restricted range and specific habitat requirements make it of conservation interest. Hardy in Zones 5a to 8b.
