Corylus avellana 'Polly O' Prohibited from shipping to Oregon. This latest release (2018) from OSU allows growers to plant in a trio of filbert varieties (Polly O, Wepster and McDonald) that will cross-pollinate and produce high yields of nuts that are perfect for shelling, for fresh eating, adding to baked goods, or surrounding with chocolate. In fact, any early-blooming filbert (excepting the incompatible Felix and Hall's Giant) will provide successful pollination. Polly O trees are the most vigorous and productive of the three varieties, so give them a bit more elbow room. Named for Polly Owen, a long-time Oregon hazelnut Industry official. Cold Hardy to USDA Zone: 5 Mature Height: 15' Sun: Full Sun to Part Shade Ripening Time: August - September Pollination: Needs an Early Blooming Pollinizer Read our Hazelnut Growing Guide
