This here is a Crepe Myrtle. They are a quintessential symbol of my growing up in the South. I bought it from a nursery here in the Midwest about 5 years ago. They assured me it was cold hardy for zone 5. I don't believe I've ever let it sit through a flood - I think I pulled & potted it during the 2009 flood. But here she is sprouting leaves after 2+ weeks under 6+ foot of water. I'm gonna take this as a sign of a good summer to come!
