Barcelona Hazelnut
A traditional commercial cultivar with large round nuts and vigorous growth. It remains popular where disease pressure is low or managed.

About Barcelona
Barcelona is the traditional Oregon in-shell hazelnut standard, producing large, attractive nuts with good shell-market appeal. It is susceptible to eastern filbert blight and is less resistant than newer Oregon cultivars.
Growing Barcelona Hazelnut
Barcelona needs compatible pollinizers and should not be planted as a single cultivar block. In regions with eastern filbert blight pressure, use resistant pollinizers and a disease-management program, then harvest promptly as nuts drop.
For planting, care, pollination, and harvest that apply to all hazelnut, see the complete guide.
