A fast-growing bramble-like vine that can produce canes up to 20 feet long. Vines contain prominent thorns. Flowers bloom during Spring in large clusters. Fruits ripen shortly thereafter during late Spring and Summer. Named after Marion County, Oregon.


Vines show freeze hardiness to 10F and lower.

Growing Environment

Vines tend to grow in large thickets and do well with support. Provide regular water and well-drained soil. Though plants enjoy full sun, keep out of very hot, dry, full sun. Plants are adapted well to cooler, maritime climates with summer heat.


Usually by cuttings or suckers. Can also be propagated by seeds, which generally come true to parent plants. Seeds can be cold stratified for 2-3 months prior to planting.


A delicious fresh fruit and one of the more common commercial blackberries in the Pacific Northwest. Fruits can also be squeezed for juice and used in desserts.

Native Range

Released in 1956, the marionberry is a USDA created cross between the Ollalieberry (Rubus ursinus) and Chehalem (Rubus x armeniaus) variety of blackberry. Today it is mostly grown commercially in the Pacific Northwest, specifically Oregon.
