Quercus garryana var. fruticosa, commonly known as Oregon White Oak, Garry Oak, or Brewer’s Oak, is a perennial shrub native to the Pacific Northwest of North America. It is adapted to a Mediterranean climate with wet winters and dry summers, often in rocky or sandy soils. This variety of Garry Oak is a slow-growing shrub that typically reaches a height of 1-3 feet (0.3-0.9 meters). It has a broad, multi-stemmed form with thick, leathery leaves that are dark green on top and paler beneath. The yellow flowers are inconspicuous and bloom in the spring, followed by acorns that are a valuable food source for wildlife.

Garry Oak is appreciated for its drought tolerance and ability to thrive in poor soils, making it a suitable choice for xeriscaping and naturalistic plantings. It is also used for restoration projects within its native range. In cultivation, it requires minimal maintenance once established, tolerating full sun to part shade. It is best suited to medium or fast-draining clay, loam, or sandy soils and requires low amounts of water, reflecting its adaptation to dry summer conditions. While it is generally disease-resistant, it can be susceptible to root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
