Quercus garryana aka Garry Oak

Taxonomy ID: 6667

Quercus garryana, also known as the Oregon white oak, Oregon oak, or Garry oak, is a member of the Fagaceae family and is found in the Pacific Northwest region of North America. Its range stretches from southern California to southwestern British Columbia, growing at altitudes ranging from sea level to 5,900 feet. There are three recognized varieties of this tree, named after Nicholas Garry, deputy governor of the Hudson's Bay Company. In the northern part of its range, Quercus garryana can reach up to 90 feet in height, while in the southern part, it is more commonly a shrub that grows up to 20 feet tall. The tree has large, lobed leaves that it sheds in the winter and is important for wildlife. Additionally, Brewer Oak is a rare houseplant that requires regular watering and well-draining soil. It thrives in direct light and should be placed less than a foot away from a window. Repotting the plant each time it doubles in size eliminates the need for fertilizers.
