Chehalem blackberry

The Chehalem berry is a cross between the Himalayan blackberry and the Santiam berry, which is itself a cross between the California blackberry and the loganberry.

It was first bred in 1936 by George F. Waldo of the USDA, who also developed the Olallie and Marion berries. The Chehalem berry is smaller than the loganberry with bright skin, a shiny black color and small seeds. The flavor is strong and especially good for frozen products. The seeds are small. It is well adapted to the Pacific Coast, and is vigorous and productive in moist, rich soil. The Chehalem has been grown to some extent commercially in Oregon.
