Olallieberries:
What is an Olallieberry?
Genetically, it is approximately two-thirds Blackberry and one-third European Red Raspberry. The Olallieberry was developed in 1949 by the U.S. Department of Agriculture at Oregon State University by crossing a Loganberry with a Youngberry. It is primarily grown in California. Because the olallieberry has blackberry on both sides of its parentage, it exhibits many of the same flavor characteristics of the blackberry. However, olallieberries are much larger in size and generally are sweeter than blackberries grown under the same conditions. It’s tart, sweet, juicy and delicious.

Loganberries:
The loganberry is a hybrid produced from crossing a blackberry and a raspberry.

Boysenberries:
A boysenberry is a cross between a loganberry, a raspberry, and the western dewberry.
