Seedlings from the Chehalem by Olallie cross have been outstanding in productiveness, having large size and high flavor. The most outstanding of these selections is the Marion Blackberry or Marionberry. The Marion was introduced by Waldo in 1956. Adapted to western Oregon, the Marionberry is named after Marion County, in which it was tested extensively. The fruit is medium to large, round in diameter 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. The quality of the Marionberry is high, with flavor superior to 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.
