A truly Oregon berry, Marion blackberries or Marionberries were developed at Oregon State University in Corvallis, Oregon. A cross between two blackberry varieties, the Marionberry has distinctively bold flavors and rich, deep colors. One of Stahlbush’s signature products, Marion blackberries are an excellent treat on their own or added to lemonades or sparkling water. They are also excellent in smoothies, desserts or breakfast items.
