'Undulata Albomarginata' is the green one with a white margin that your grandmother grew. It's been around for a long time. Most of us have at least one plant and I'm no exception. I've got four and I've got them for the duration as the roots are mired into the Linden tree roots. This is an old variety, but it is still very nice and it blooms well. Please feel free to share your photos of this hosta.
