This little iris is one of the first to bloom at my house. It is planted along the driveway in a rocky dry area in a patch of weeds. It is thriving on neglect! I believe this came from the Big Sky Iris Club plant sale, but it had no identification. I posted the image on a Facebook Iris group and someone told me it is iris lutescens - a species that was found in the wild on the Crimean peninsula. It was identified by a French botanist in 1789.
