Has anyone else had the problem of rather weak stalks on this iris?? Maybe mine was growing in too shady a place. But compared to the sturdy stalks of Dusky Challenger this one has fallen over quite a bit for me.

Alas, I was also expecting a BLACK flower, but I am thrilled with the dark, dark purple. Mine tend to fade out quickly in the Texas sun, but they are still stunning. I have them planted against a background of coreopsis "Sunshine" and the black/purple/golden yellow combination always makes the neighbors stop and look!
Superstition is a lovely dark purple and grows well in the Oklahoma South East Oklahoma area.
I really wanted a more black by what the photo showed on the package it was a really dark black but it's a really dark purple.
It does take a good two years before any blooms apear. Bought in 2001 and bloomed in 2003.
I have also seen the color as:
Dark Ebony beauty hint of Maroon.
Ebony Standards and Falls w/ dark purple veins and blue-black beards.

One of those old reliables that you love to have in your garden. It may be cold weather that has all the "blacks" open so they look black. This and Dusky Challenger were black when they very first opened.
