About Jefferson
Jefferson is an Oregon State University hazelnut developed as an eastern filbert blight-resistant replacement for Barcelona. It combines large nuts, good kernel quality, and high yield efficiency.
Growing Jefferson Hazelnut
Jefferson requires compatible pollinizers because hazelnuts are self-incompatible. Maintain a pollinizer plan with overlapping winter pollen shed, and monitor for filbert bud mite and bacterial blight despite its strong eastern filbert blight resistance.
