Well, for now it's just a note in my gardening notebook, for a future shade / wildfower garden. I hope to have a space in the back woods as a shady place to sit and converse, or just read. Many projects that are more urgent are in line ahead of it. Then i need to find a nursery that sells that plant!
In the meantime, I hope that wild clump of plants stay safe (I initially thought it was one plant; wrong, it is six or so, in a clump).
I'v taken some notes on the soil around that plant, it is growing on Cecil sandy loam, which is the soil in my back yard and woods, but it's just down slope from some Davidson clay loam which usually has a more neutral pH. The pH is probably why the plant is living where it is.
