Here's an iris no garden should be without. Even blacker than the famous black tulip, "Queen of the Night", "Night Ruler" glistens with dark magic among other flowers and plants.  Not sure why these photos turned out to be more dark purple, rather than black.  But when these photos were taken, these blooms appeared to be very black to human eyes.  

Your neighbors will think you're a master gardener with such a "rare-looking" beauty in your flowers, but in reality, it's requires no special care.

See how Night Ruler's color, a deep inky black purple with a pervasive black sheen, thoroughly permeates the flower, beards and all. It is its copious ruffling which truly separates it from the other dark Iris.  Many double-socketed buds are presented on three widely spaced branches.
