Golden Japanese sweet flag is grown primarily for its fragrant and attractive greenish-yellow foliage, which resembles that of an iris. Insignificant greenish-yellow flowers bloom from June through August, giving way to inedible red berries in the fall. The plant grows to 1 foot high and spreads to 1 foot. Grow in moist soil in full sun to part shade, or use it at the edge of ponds or bogs where it will spread by rhizomes.
