The Garry oak is the largest oak species in the coastal region of the Pacific Northwest. It grows in low valleys or plateaus, away from coastal spray, preferring loamy, rich, and moist soils. However, it can also thrive in dry soils, heavy clays, winter-flooded riverbeds, and mixed forests. At higher altitudes, it is reduced to a shrub form. The species is highly tolerant of heat and drought. 

ADeciduous Tree: It can reach heights of up to 25 meters. Leaves: Measuring 2.5 to 15 cm long and 1.5 to 8.5 cm wide, with obovate (inverted oval), elliptical, or nearly rounded blades. Acorns: Oblong to globular, 1.2 to 4 cm long and 1 to 2.2 cm wide. They are solitary or grouped in clusters of up to three, subsessile (nearly sessile), or occasionally borne on a peduncle 1 to 2 cm long. They are housed in cups that enclose up to one-third of the acorn.
