HAVE: Cynoglossum virginianum,Wild Comfrey
This is not a showy plant, but a colony in a woodland setting is charming. I have 15 seeds or seedpods - no idea whether the little round white burs break into smaller seeds or not. Mine both re-seed themselves and come back from the root. These seeds are already stratified and should be scratched into surface of small area this month. I still have a few other types of seeds on my trade list left as well.
