Description

Thomas black walnut is a deciduous tree in the walnut family (Juglandaceae) and is a hybrid of the native black walnut.

The tree grows 40 to 65 feet tall and wide in full sun and average well-drained soils. It is deer and verticillium wilt resistant. The taproot contains juglone, which might inhibit the growth of some plants such as azaleas, peonies, some vegetables like tomatoes, and blueberries beneath the tree's dripline. 

The spring flowers are followed by large, thin-shelled, easy-to-crack nuts with excellent flavor.

Use Thomas as a shade tree in meadow and woodland locations. It also can be used in butterfly, edible, native and nighttime gardens.

Diseases, Insects and Other Plant Problems: Under pressure in some areas from thousand cankers disease. Other potential diseases include anthracnose, bacterial blight, root rot, canker, leaf spot and shoot dieback. Watch for aphids, fall webworm and a variety of foliage chewing caterpillars.
