Do hardy geraniums perform well in Iowa?
While not widely planted in home gardens, hardy geraniums (Geranium spp.) are attractive, easy-to-grow perennials. Numerous species and varieties are available. Plants typically bloom in late spring/early summer. The 1- to 2-inch-diameter flowers may be white, pink, magenta, purple, or blue. Several double flowering varieties are also available. Hardy geraniums commonly grow 6 to 12 inches tall. In fall, the foliage of many varieties turns to shades of yellow, orange, or red. Hardy geraniums prefer moist, well-drained soils and partial to full sun. They have few insect or disease problems.
Hardy geraniums should not be confused with common garden geraniums. Garden geraniums are not “true” geraniums. Garden geraniums are annual plants which belong to the genus Pelargonium.
