In 1945, around the time when the Dake Brothers purchased that small dairy and ice cream business starting what we know today as Stewart’s Shops, something else was happening in the Northwest corner of the country.

What is a Marionberry?

A Marionberry is a cross between a Chehalem blackberry and an Olallieberry; named after Marion County in Oregon which is fitting as they are only grown in Oregon. This medium-sized blackberry is sweeter and juicier than most other blackberries and can be reddish to deep black in color. Marionberries tend to be firmer and a bit larger than other varieties of blackberry.
