Turkish hazelnut

Turkish hazelnut is an excellent hardy tree for lawns, street plantings, and urban conditions.  Its heavy-textured, dark green foliage is free of insect and disease.  This tree is also pH adaptable and tolerant of heat, cold, and drought once it is established.
 Aside from its outstanding cultural tolerance, Turkish hazelnut yields attractive male catkins in early spring and striking beaked fruits.
