Twisting gray-brown branches give Corylus avellana Contorta a clear outline through winter, when hanging golden-yellow catkins appear before the leaves. The slow-growing, rounded shrub reaches about 8 to 10 feet tall and wide, with arching outer branches that become more pendulous with age.
Broad, crumpled green leaves cover the framework in spring and summer before turning yellow in fall. Brown nuts may follow in late summer, although crops are often sparse. A prominent border position or large patio container keeps the unusual stems easy to see, and cut branches work well in winter arrangements.
Plant in full sun or partial shade and use moist, well-drained soil. Water regularly while roots establish, then allow occasional drying. Remove straight shoots from the base so the contorted framework remains dominant, and prune damaged wood at the end of winter. The pollen and nuts may trigger allergies in sensitive people; avoid eating the nuts with a known hazelnut allergy.
