Pelargonium x hortorum 'Maverick'
flowerThe zonal geranium is the quintessential summer container flower, the bold red, pink, or salmon geranium that fills window boxes, porch pots, and beds across the country. Despite the common name it is a Pelargonium, not a true hardy geranium. The Maverick series is bred for garden performance and grown from seed, producing compact, well-branched plants topped all summer with large rounded flower heads over softly scalloped, often zone-marked leaves. Sun-loving, heat-tough, and drought tolerant once established, it is a tender perennial grown as an annual in most of the country, blooming from spring until frost with a little deadheading.

Grow zonal geraniums in full sun, at least six hours, in fertile, well-drained soil or a good potting mix; in the hottest climates a little afternoon shade prevents leaf scorch. They are heat and drought tolerant once established - let the soil dry somewhat between waterings, as constantly wet soil invites disease, and they are excellent in containers where that is easy to manage. Feed every couple of weeks during bloom for the best flowering. Deadhead by snapping off the whole spent flower stalk at its base to keep new heads coming. They are tender perennials hardy only in zones 10 to 11, so grow them as annuals or overwinter favorite plants indoors on a bright windowsill.
🌼 Have a different variety?Cultivars of the same species usually share the same basic care — they differ mainly in flower color, height, and bloom form, not in how you grow them. So this guide still applies even if your exact variety isn't the one shown.

Botrytis rots flowers and leaves in damp, crowded conditions - give airflow, water at the base, let soil dry between waterings, and pick off spent blooms and dead leaves
Cluster on buds and tender growth - rinse off with water and encourage ladybugs
Geranium budworm caterpillars bore into buds so they never open - pick off affected buds and the small caterpillars by hand
Zonal geraniums are grown for bedding and container display rather than for cutting. The key task is deadheading: snap off each whole flower stalk at its base once the head fades, which keeps a steady supply of new blooms coming all summer and keeps the plant tidy. To carry a favorite plant over, dig it before frost, pot it up, cut it back by half, and keep it in a bright, cool spot indoors through winter.
A purely ornamental container and bedding flower grown for its bold, season-long color and heat toughness. Bees and butterflies visit the open flower heads, but its value is its reliable display in pots, boxes, and beds.
Zonal geraniums (Pelargonium) are mildly toxic to dogs, cats, and horses - the geraniol and linalool in all parts can cause vomiting, loss of appetite, and skin dermatitis in pets. They are not toxic to people. Keep pets from chewing the leaves and flowers.
