The 'Thornless Evergreen' blackberry, discovered in 1926, is now among the most important small fruit crops in Oregon. The success of this selection, aside from its thornlessness, is due to it adaptability to western Oregon climatic conditions and to its high yields of acceptable fruit for processing purposes. The cut-leaved thorny form of the 'Evergreen' blackberry is widely distributed in the wild, and is assumed by some to be a native plant. However, David Douglas (4), the first botanist to study the native plants of the Pacific Northwest, did not describe any plant similar to the 'Evergrren' blackberry during his visit to western Oregon in 1825 and 1826.
