Juglans nigra bark and leaf, Robert H. Mohlenbrock. USDA NRCS. 1995. Northeast wetland flora: Field office guide to plant species.

Cultural Practices:
As is typical among the walnuts, the butternut secretes a substance (juglone) that prevents close-by plants to grow.

Blooming Habits:
The male flowers are long catkins, 2.4 to 5.6 inches long (6-14 cm). The female flowers are yellowish green, on short spikes, close to the end of the twigs. The black walnut blooms in the spring (April to June).

Fruiting Habits:
The fruit is a elongated nut, 1 to 1.6 inches in diameter (2.5-4 cm), containing a tasty, oily seed, ripening in the fall (September-October). It generally stays on the tree until early winter. It is surrounded by a very hard thick shell. The husk is oblong and sticky.
