Kinda late, I know, but I am separating some huge clumps that I didn't get to before. They are mostly ones I have coming out of my ears, so no big loss, right? One plant that i noticed has an interesting feature; It grows a "neck" for each new rhizome that lifts it up and away from the crowded rhizomes growing underneath it. Not sure what it is, but it is planted in a special place so I can ID it next year. These clumps are the thriver/survivors I have had for years, and it looks like most patches of rot that I noticed earlier have calloused over rather than spread. I suppose some irises are much hardier than others. Which ones do you grow that seem to survive no matter what?
