I live here and have helped plant one of the gardens. The pattern was already worked out and the plants ordered, we were just the planting crew. Each one is different and a different volunteer group plants them. If you come, stop by the visitors center and get a booklet that shows what to see in the area. And don't forget the quilt shops. I'm still thinking there are 13 within driving distance.
My avatar is Mt. Shasta where I was raised in California. No mountains in Indiana.
