Pelargonium ×domesticum, commonly known as Regal Geranium, is an evergreen perennial herb. This plant is a complex hybrid, primarily derived from Pelargonium grandiflorum and Pelargonium cucullatum, both of which are native to the fynbos region of South Africa, characterized by heathland, shrubland, and renosterveld. It typically grows to a height of 1-3 feet (0.3-0.9 meters) and a width of 1-2 feet (0.3-0.6 meters). Regal Geraniums are known for their large, showy flowers that come in a range of colors including pink, purple, and red, blooming mainly in the spring. The foliage is often lobed or toothed, adding to its ornamental value.

Regal Geraniums are favored for their beautiful, large flowers and are commonly used in container plantings, hanging baskets, and as bedding plants in gardens. They are relatively easy to maintain, requiring only regular watering and occasional deadheading to promote further blooming. These plants prefer well-drained soil and can tolerate a variety of soil types, though they thrive best in loamy soils. While they can grow in full sun to part shade, they benefit from some afternoon shade in hotter climates to prevent leaf scorch. It’s important to avoid overwatering and to provide good air circulation to prevent fungal diseases. Regal Geraniums are not known for aggressive roots or significant disease problems, but they can be susceptible to geranium rust and botrytis blight if conditions are too damp.CC BY-SA 4.0
