Sweetflag has horizontal stems that grow underground. The leaves are simple, bright green, sword shaped, and have a sweet scent when they are broken open. They grow two to six feet long and a half inch wide. Leaves have a midvein and two to six more parallel veins that are visible when leaves are held up to the light. Flowers are typically yellow green in color, look like a tightly packed spike about two inches long, and grow from the leaves.
