Adlay is a robust grass with stout, fibrous stalks that can reach heights of 3 to 4 feet (90 to 120 cm). The long, narrow leaves are lance-shaped, enveloping the stem with a green to gray-green hue. Its most distinct feature is the bead-like, tear-shaped seeds enveloped in glossy, hard casings when mature. These seeds are typically a pearly white, though they can vary in color. Each seed case is roughly 0.3 to 0.5 inches (8 to 12 mm) in diameter, with a groove on one side.
