Garry Oak captures the charm of Western Oregon. Centuries of cold winters, hot dry summers, winds and rain shape this nostalgic tree.

The twisted and gnarled branches hold the mysteries of time past - the perfect oak for the Northwest, but increasingly rare in the wild.

They are found on dry hillsides along the coast from BC to California and inland to the Sierra Nevada in USDA zones 6-9.

They prefer full sun and tolerate drought and harsh winds.

Growing slowly to 90,' Garry Oaks can live for 500 years.

Their leathery dark green leaves, 3 - 6," turn brown in the fall. The leaves are very high in nutrients (especially phosphorous) and make exceptional mulch.
