Bluejack Oak

Quercus incana

Bluejack oak is a small sandhill oak of the Southeast, named for the blue-gray cast of its narrow leaves. A drought-hardy host tree of deep, dry sands and longleaf-pine sandhills. Its acorns are traditional food once the bitter tannins are leached out and the seed ground into flour.
