Hardy geraniums are adaptable perennials with spreading mounds of foliage and a long season of flowers, useful for borders, edging, ground cover and informal planting.
Hardy geraniums are dependable border perennials that flower generously, knit between larger plants and cover bare soil without demanding a rigid planting style. Different forms work as edging, ground cover or loose mounds through mixed borders. They are particularly well suited to Irish gardens because many tolerate regular rainfall, cool summers and partial shade. Good drainage still matters for some species, but the group contains options for both sunny and more shaded sites.
