Broomcom is actually a variety of upright grass of the species sorghum referred to as Sorghum vulgare, or S. bicolor variety technicum, belonging to the family Gramineae and cultivated for its stiff stems. Broom bristles are derived when these stiff, tasseled branches—that bear seeds on the ends—are harvested and dried. The seeds are edible, starchy, and high in carbohydrates. They can be used for human consumption (in cereals) or for animal feed. The tasseled stalks, used in the manufacture of brooms, can grow 2-8 ft (0.61-2.4 m) tall. Sorghum is especially valued in hot and arid climates due to its resistance to drought.
