As you may have noticed, assuming you live in Michigan and have a pulse, the record breaking heat in March was followed by some very cold nights in April. Did it take a toll on any of your plants? I've seen complete and partial defoliation on some japanese maples, and I noticed a tree-of-heaven (Ailanthus altissima) with liquified leaves. Some of my odd-ball asian perennials took a hit, including my two exotic species of mayapple (Podophyllum). My Kirengeshoma palmata (sorry, no common name) was reduced to mush, but it serves me right -- it had no future in my dry sandy soil. I was saddened to see damage to my toad-lilies, but it doesn't appear severe. And of course whatever is left of the magnolia flowers has become quite the embarrassment. (Late breaking news: caller reports that her tulip-tree has suffered 75% defoliation).
