Good news -- the blossoms survived, at least most of them. A yearling deer on a taste adventure, I suspect, came by and nibbled off the top bloom. If it weren't for the young deer checking out what's good and what isn't, "deer resistant" plants would have a better chance.
"Magical Encounter" is the iris that went through the uprooting and nibbling experience. She is supposed to be about three times this tall; I'm hoping the soil amendments will make a difference for next year. I bought her last summer from Shreiner's Iris Gardens, and I am glad the rhizomes I got from them were so sturdy and reproductive.
