Zag Zag Iris

I received a iris simular to the Lousiana in a trade.
The person making the trade called it the zig zag iris
Does anyone know of its real name

Thanks Granny for the idenity and also the web site.

I have a brevicaulis and it came back the second year so I hope it continues to thrive here. I thought it was a risk in zone 5. I'll know in a few months. Here it is last year. The flowers tend to fall and grow low but I don't care because the color combo is phenomenal!

Here's another source of information on Iris brevicaulis. http://www.zydecoirises.com/Species/Brevicaulis/Brevicaulis.htm
