Densely white wooly leaves and a multitude of 3/4" purple-petalled flowers. Lychnis means "lamp" - the leaves were once commonly used as wicks in oil lamps. The seeds are anti - asthmatic, diuretic, and vasodilators. They contain Khellin, from which pharmaceuticals for asthma are made. An old garden favorite; easy because it reseeds. Very attractive.
