Surely not just perhaps, Kate.
I happily spend hours looking at Mosses, Clubmosses, Lichen and Wildflowers including Orchids at our place in Pennsy. I have seen it a few times - we have very rocky, poor soil on some of the slopes. If for any reason the ground was turned over, one saw stunted Wildflowers and Lichen ( mainly Cladonias) making their appearance. Through the years the soil becomes slowly enriched and that is when we see Spiranthes cernua, a local Orchid popping up. Many times we see Cladonia cristatella, those pretty little red-tipped Lichen right nearby the Spiranthes.
You have read along in this thread? Elaine participated here, but perhaps others might find it interesting also.
