Gardeners' Notes:


On Apr 30, 2014, vossner from Richmond, TX (Zone 9a) wrote:

Rating it neutral as it may be a one season wonder in my garden. I planted it in a shady area of my garden as I've read that some zone 9a gardeners have had long term success planting iris germanica in shade. We shall see. Deserves a positive because the color and form are absolutely stunning. I got it about 2 weeks ago and I suspect the only reason it bloomed is b/c it already had a bud.

'Superstition' is dark burgundy, almost black--not dark purple. Most of the photos on DG don't do this beauty justice. This is one of my all time favorites, mainly because of its gorgeous color.

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.

Extremely dark purple, in the right light it looks black, and this year (2006) with the cooler weather right before blooming the falls are nearly black even under fluorescent lights.

Great iris, blooms like crazy! It even re-bloomed in my zone 5 garden in November!

Superstition has been remarkable for me here Zone 4

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 Iris by Schreiner 1977.

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.

Large blooms, impressive dark color just short of black. Blooms well in part shade, 2nd year after planting.
