Hornbeam trees (Carpinus spp.) are elegant, slow-growing deciduous trees known for their dense foliage, smooth gray bark, and excellent adaptability in both formal and natural landscapes. Ideal for USDA Hardiness Zones 4–9, hornbeams thrive in full sun to partial shade and well-drained soils. With attractive green leaves that turn yellow to orange in fall, hornbeams provide multi-season interest and strong visual structure year-round.
