Silene Italica

A rather unusual campion with thin dividing stems, carrying many small white flowers which open from long slim buds, the calyces being striped in red. As they age, the petals twist like small propellers! Originating in the Alps and mountains of Provence, it has spread including to a location where it is a locally naturalized alien, discovered in 2005 on a coal mining spoil heap near Charleroi (Damprémy)!
