With huge, velvety deep purple flowers, 4-6" across, adorned with delicate gold highlights on each petal, Black Gamecock Iris is an award-winning beauty. (American Iris Society, Mary Swords DeBallion Medal, 1989). This Southern native, noted for its unprecedented vigor, will multiply quickly if sited in consistently moist to boggy soil, or even shallow water. This makes it a perfect choice for naturalizing along ponds and streams, and an outstanding addition to aquatic gardens. Louisiana Irises usually bloom after Siberian and Tall Bearded Irises are finished, thereby extending the iris season. What's not to like about that?
