Scientific name: Corylus colurna
Turkish filbert is also known as Turkish hazel or Turkish hazelnut. This tree is a member of the birch family (i.e., Betualaceae) and originates from southeastern Europe to western Asia. It is a medium to large, slow-growing, deciduous tree. This beautiful pyramidal tree has low, horizontal branching and typically grows 40-50 ft tall (up to 80 ft less frequently) by 30-50 ft wide. In early spring, yellow flowers bloom. The leaves are bright green, semi-glossy, and double-toothed and have hair on the veins beneath. In fall, nuts appear and are popular with wildlife. Tolerant of urban conditions, Turkish filbert is recommended as a lawn, shade, or street tree. This tree grows in plant hardiness zones 4-7.
