Acquaintances who moved to the Atlanta area from "up north" a few years ago bought a stately old house, with a large garden. It was March and green things started to emerge from the soil all around the house, and they had no idea what they were dealing with. "This looks like an Aster, or maybe it's a Daylily - who knows?"
Master Gardeners typically do know. But not many of them travel all around the area to look at little green things popping up in gardens and telling the homeowners what they've got and how to take care of it. Recently, I found someone who does! Shannon Pable in Buford has a landscape design business and plant IDing is one of the services she provides her clients. Check out her web site and get in touch with her, if you need help.
