Recently, I visited a friend's garden. Several years ago, I gave her some iris rhizomes when I was dividing what was already planted here at my home when we moved in (back in 2003). She planted the rhizomes and has a beautiful garden in Bridger, Mt. These iris are all "Historic" - meaning they are older varieties. I have not been able to actually identify most of them, but I believe the one above is called "City of Lincoln". It had been discarded in the ravine below our house, where it thrived. I dug them up and tried them up near the house. They have proliferated in Joan's garden.
