Very dark purple, very ruffled. Mine is even more ruffled than these pictures. Velvet texture. This is one of my favorites in this year's garden.

One of my favorite tall bearded irises. It is a terrific grower and has beautiful waxy, flowers black with a slight blue shimmer. And lots of ruffles on the flower. Be sure to plant it in the sun. It get lost if it is in the shade!
