Narrative
Barney Douglass was a private blackberry breeder who lived in Hillsboro, Oregon. Giant Douglass is a nonpatented, thornless trailing blackberry selection from Barney's program. The parents were Sander x Lawrence, neither were cultivars, but he prefered to give his selections names than numbers. In our plots, the fruit quality was excellent, yields were very good and the plant was not susceptible to any particular diseases. Thornlessness was derived from Austin Thornless. Chad Finn 07/2003.
