Geranium cantabrigiense "Karmina"
Geranium cantabrigiense "Karmina" is a hardy Geranium that looks especially charming where it has a wall to spill over or stones to crawl between. The smaller, darker blooms of "Karmina" keep coming and coming as long as you deadhead; it also spreads nicely, making a most attractive ground cover. Sun or shade. Zones 4-9. Quarts.
