Seedlings from the Chehalem-by-Olallie cross have been rather successful – producing big berries that are full of flavor. The most outstanding of these selections is the Marion Blackberry or Marionberry. Introduced by George F. Waldo in 1956 and adapted to Western Oregon, the Marionberry is named after Marion County, where it was tested extensively. The berry is medium to large, round and somewhat longer than wide. The Marionberry is a trailing vigorous grower, generally producing only a few long canes which grow up to 20 feet. The spines are large and numerous, and fruiting laterals are long and strong, with many fruit. The Marionberry produces up to 5-6 tons per acre. Marionberries are quality berries, with a better flavor than the Boysen or Evergreen. Marionberries are well-suited for use in local fresh markets and for commercial or home canning, freezing, pies, ice cream flavoring, jams, and jellies.
Fresh season is typically July 10 – August 10.
