The Combination Hazelnut tree is a unique hybrid of the ‘Yamhill’ and ‘Jefferson’ hazelnuts, offering the best of both varieties in one tree. In late summer and early fall, it produces edible brown nuts enclosed in leafy, hairy green husks. In late winter and early spring, the tree showcases long, yellow catkins that attract bees and other insects. The Combination Hazelnut is a great addition to home orchards, backyard gardens, or shrub borders.
