Cattail millet is a type of millet that is grown extensively in Asia and Africa, primarily for its edible seeds. The plant is also known by various other names, including bulrush millet, pearl millet, and finger millet. The term "bulrush millet" is derived from the plant's association with bulrushes, while "pearl millet" is so named because of its resemblance to pearls. The name "finger millet" is inspired by the shape of its seed, which is shaped like a finger. Other synonyms for cattail millet include clover millet, foxtail millet, and barnyard millet, depending on the region and language. Despite the different names, all varieties of millet are gluten-free, making them a popular alternative to wheat and other cereal grains.
