I have removed Gnu's Flash from my garden. Every year it falls over because the stalks are weak . An iris is no good to me if it's laying on the ground. The bloom also seems to lose its shape quickly . The bloom is wide open by the second day and all you see are style arms.

This has turned out to be one of my favorite irises. It bloomed for me the first time last year and I entered the stalk in a show, my first ever. I knew nothing about showing iris, but I got a ribbon with it anyhow. I love its appearance and its ease of growth.

There are Iris I choose for their appearance, and those that I choose for their name alone. This one I chose for both reasons. It has proved to be quite the crowd pleaser with people who walk by on the sidewalk, both because of the color, and for the length of it's bloom time. The flowers are huge, and at one point I had to stake one stalk because it was so top heavy. I'd recommend this one for anyone looking for something a little different.
This is doing very well here in northern Arkansas. A nice edition to any iris collection. Light tan standards with violet infused midribs. Streaked silver-white. Falls dark violet with creamy white streaks. Yellow beards. Color description according to Cooley' Garden.
