Mustard is an annual or biennial and grows to be 2-4 feet tall and 1-2 feet broad, blooming from May to September. Mustard is the third largest source of vegetable oil in the world. For this reason, it is most commonly grown in large fields, but the plant often escapes and naturalizes as a weed. The leaves are approximately 20 inches long and are flat. The yellow flowers have four petals that become sickle-shaped seed pods.
