Hardy or perennial geraniums offer months of pretty blooms, often from late spring until fall. These low-maintenance perennials are often low growing with attractive foliage, making them ideal for planting in the front of flowerbeds, lining a walkway, spilling over a rock wall or as a ground cover. They're also a top choice for planting in front of roses. Hardy geraniums' flowers attract butterflies, bees and other beneficial pollinators. For best results, plant hardy geraniums where they will receive full sun or in a partially shaded area that receives direct sunlight for several hours each day.
