![]() | Chinese Wingnut Tree - Pterocarya stenoptera Walnut Family: Juglandaceae USDA hardiness zones: 6B through 11 Insects & Spiders Home | Tree Pictures | Tree Index | Rosaceae Index | Juglandaceae Index | Oaks & Beech |
| Chinese Wingnut grows to 70 feet as a deciduous tree with large, substantial branches which spread as wide as the tree is tall. The 6 to 12-inch-long leaves are composed of many, finely-toothed, oval leaflets. The leaves do not display any appreciable fall color. Of particular interest are the 6 to 12-inch-long seed clusters, green strings of winged seeds suspended below the branches which turn brown and fall in autumn. The tree grows at a phenomenal rate. The trunk can reportedly grow to at least eight feet in diameter. |

Chinese Wingnut may perform well as a street or shade
tree but the aggressive roots may make it unsuitable for
use in a lawn or garden. It should be considered for
broader use as an urban tree but it is largely untested,
so use it with caution. Locate it well away from (10
feet or more) a sidewalk or driveway so the
large-diameter surface roots will not lift the concrete
or asphtitle. Prune early in the life of the tree to
form a good, strong structure by spacing major limbs
several feet apart along a central trunk. Do not allow
these limbs to grow more than about two-thirds the
diameter of the trunk to encourage formation of a strong
branch collar. |
