Each leaf measures 1.5 to 4 inches (3.8 to 10 cm) in length and 1 to 3 inches (2.5 to 7.6 cm) in width. The margins can be entire, wavy, or coarsely dentate, and the surface may be either hairy or smooth.
The flowers of black nightshade bloom from May to August, displaying tiny, star-shaped blossoms with 5 white petals sometimes flushed with purple or pale blue. Each flower has a yellow-green center and measures 5 to 7 mm (0.2 to 0.28 inches) in diameter. They are arranged in umbel-like cymes, featuring 3 to 12 flowers per stalk. The flowers also boast five stamens with prominent yellow anthers, adding to their distinctive appearance.

The fruit of black nightshade is a delicate, globular berry approximately 0.25 inches (6.35 mm) in diameter, borne in clusters.
