- Description
-
Chinkapin is a monoecious multi-stemmed, thicket-forming shrub or small tree with spreading lower branches and ascending upper branches. If grown as a tree in can reach 15-30 feet tall. It is resistant to the chestnut blight and can usually recover if infected. It can be found from the coast to 4500 feet elevation in the mountains.
Chinkapin nuts are palatable to humans as well as wildlife. They have a sweet flavor and are eaten by many birds and mammals. They can be difficult to harvest and are not grown commercially. Its wood is light, hard, close-grained, and strong. It is used for fence posts and fuel although it is not timbered because of its small stature and scattered occurrence.
This tree prefers dry, acidic to neutral, well-drained soils in full sun to partial shade. Use as a small shade tree or to provide food for yourself and wildlife in a lawn or naturalized area.
Insects, Diseases, or Other Plant Problems: Chinkapin is moderately resistant to chestnut blight, but fewer trees are reported each year due to the inhibitory effects of the fungus.
