Silene dioica 'Rollie's Favorite' is an interesting Campion hybrid. A recent introduction from Herbert Oudshoorn of the Netherlands, it is a long-blooming plant, forming a low mound of dark-green, oval leaves, with clusters of starry, rich-pink blossoms, each with a white eye. Flower heads resemble Summer Phlox.
