Latin Name: Pelargonium × hortorum

Commonly known as Zonal Geranium, is a classic flowering plant prized for its bold, rounded flower clusters and distinctive horseshoe-shaped leaf markings (“zones”). This sun-loving perennial (often grown as an annual) produces vibrant blooms in shades of red, pink, white, salmon, or purple from spring until frost.

Ideal for beds, containers, and window boxes, zonal geraniums thrive in full sun (6+ hours daily) and well-draining soil. They tolerate drought once established but benefit from weekly watering and monthly feeding. Their upright, bushy habit (12–24 inches tall/wide) makes them versatile for both formal and casual gardens.

Hardy in USDA zones 10–11, they’re typically overwintered indoors in cooler climates. Low-maintenance and heat-tolerant, they resist pests like deer and rabbits. Modern cultivars (e.g., ‘Americana’, ‘Calliope’) offer improved bloom size and disease resistance.
