We have had changing weather. It got hot real early, then we had a couple nights of frost just last week. The Iris in question is on the north side ofthe house, as well. I was surprised that my full-bloom blooms didn't get damaged with that frost (two nights of it), so maybe that accounts for it. I'll leave it where it is and give it another year. It's a very young plant -- one fan, one bloom stalk.
I do use RoundUp, and I do it use around my Irises. But I am oh-so-careful -- only spray on still days, low-volume spray near the ground but not near the foliage, etc. I didn't know that it could deform buds, although I learned some years ago that it can sure kill Irises!! Had a grouping of Irises around my mailbox, and it got invaded with Bermuda grass. Very difficult area to do any digging to remove the Bermuda that way, so I decided to spray the area with RoundUp. Well -- it killed the Bermuda alright, but the Irises as well. :sad:
RoundUp is some serious business.
