Thanks, Sheila -
I call that little guy "the GA butterfly" cause it's our state butterfly. So much easier for me to remember than "Eastern Tiger Swallowtail" when I was first taking their pics. I forget why my nursery recommended Hoppy to me, other than it being a native that they thought would do well in my yard, and what I call the "unusual factor," but he's thriving, I think. Can't say he's grown much since planting him a year or so ago, but he's still alive, and in my world, that equals thriving.
And yes, I call him "Hoppy" -- it's easier to talk to my plants if they have names.
