This is a native tree for my part of the country. I have 3 very large ones growing around the house .... great summer shade ... lots of fall clean up. I don't have any grass to water which is a good thing for these oaks .... they do not like lots of water in the summer ... it will kill them. I don't have this as a positive remark since these are native trees and they are quite messy all year long in a yard setting.

This tree has gnarled branches which look neat in winter. It doesn't have especially showy leaves in autumn. Summer leaves are dark green. It can live to 500 years or more.

The famous botanist, David Douglas, discovered this tree and named it for his friend, Nicholas Garry, of the Hudson's Bay Company.
