- Description
-
Water Hickory is a large native deciduous shade tree in the walnut family. It is a major component of wetland forests now in the southeastern US, because of the selective cutting by the lumber industry. It is considered important in cleansing water runoff during flooding. It is very tolerant of wet soils but grows best on well-drained moist soils near rivers and other waterways. It can spread aggressively by both seeds and sprouts from the roots.
The spring male and female flowers give way to nuts that are bitter but enjoyed by waterfowl and small mammals. It is slow-growing and generally doesn't produce nuts until after the age of 20 years. It can reach heights of up to 100 feet or more with a narrow irregular crown. Propagate this tree by moist stratification of the seeds.
If you have a pond or stream or other moist to wet areas with plenty of space this tree would work well for you. It has good wildlife value. It is a food source for the larvae of moths, including Luna moth (Actias luna), Hickory leafroller moth (Argyrotaenia juglandana), and Royal walnut moth (Citheronia regalis)
