'Black Gamecock' is the most famous of the Louisiana Irises, noted for its velvety, purple-black blooms set off by slender, gold highlights. Native to the south, its flowers measure up to 6" across and appear in spades just as summer arrives. 'Black Gamecock' thrives in well-watered gardens or naturally wet areas and is noted for its unmatched vigor. An easy choice for naturalizing along pond edges and throughout wet meadows.
