The four most popular varieties of geraniums are:
Zonal geraniums – the classic geraniums you recognize. With single or double blooms in white, pink, red, burgundy, yellow, orange, and purple, Zonal geraniums are easy growers, heat tolerant, and drought-resistant. The Classic, Tango, and Rocky Mountain cultivars all come in a wide variety of colors.
Regal geraniums – also known as Marsha Washington geraniums. They feature large multicolored blooms and are considered a delicate variety, yet they thrive with the proper care. They perform best in cooler areas and will not flower in hot summer temperatures. Unique cultivars include Ace High, Brown’s Butterfly, Blue Orchid, and the Coral Sea.
Ivy geraniums – create abundant mounds of cascading flowers. The leaves are shiny and resemble ivy. The single, semi-double and double flowers bloom from early spring to the first frost of fall. Try Summer Showers, Contessa, and White Mesh cultivars for abundant blooms.
Scented geraniums – have scented leaves with a velvety texture. While they don’t bloom as profusely as other varieties, they are a favorite of many gardeners. Although there are endless variations, popular scents include roses, apricots, apple, and mint. The cultivar name often hints to the geranium’s scent, such as Chocolate Mint, Ginger, Lemon Balm, and Lime.
