Black Gamecock

Iris louisana 'Black Gamecock' grows in my rain garden and has formed a huge patch but it also grows well under the drip of a leaky gutter. So, give it some moist soil and you will be rewarded by these velvety royal purple blooms in May. The foliage is good looking most of the year.

I first saw Louisana Iris many years ago at Bellingrath Gardens near Mobile, Alabama.
It grew in the bayou in several inches of water.
Tony Avent says in his catalogue that it grows to 5ft, mine gets 2-3 ft but I guess in water it would grow taller. Multiplies nicely in a sunny damp place
