The olallieberry (pronounced oh-la-leh, sometimes spelled ollalieberry, olallaberry, olalliberry, ollalaberry or ollaliberry) is a cross between the loganberry and the youngberry, each of which is itself a cross between blackberry and another berry (raspberry and dewberry, respectively).
The original cross was made in 1935 by S. J. Harvey with the United States Department of Agriculture Agricultural Research Service (USDA-ARS), who ran the cooperative blackberry breeding program between the USDA-ARS and Oregon State University. Selected in 1937 and tested in Oregon, Washington and California as "Oregon 609", it was named "Olallie" and released in 1950. While developed in Oregon, it has never been very productive there and is therefore primarily grown in California.
Formally named "Olallie", it has usually been marketed as olallieberry, just as "Marion" is sold as marionberry.
"Olallie" means berry in the Chinook jargon.
Olallie Lake in Oregon's Cascade Range is named after the Chinook term due to the abundance of berries in that area.
