zonale

Zonale is a horticultural term used to describe a class of pelargoniums known for a distinct color pattern on their leaves. The name comes from the characteristic zone or ring of color that appears across the leaf blade, typically creating a contrasting area in the center or along the margins. The term is most commonly associated with Pelargonium zonale, a South African species, and with the broader group of cultivars marketed as zonal geraniums (Pelargonium × hortorum in many cases).

Leaves in zonale varieties are usually rounded or lobed and display a variety of zonal patterns, including a darker center with lighter surrounding areas or reverse arrangements. Flower heads appear in clusters and come in many colors, such as red, pink, white, and orange. The overall plant form is compact to upright, making zonale pelargoniums popular for borders, containers, and hanging baskets.

Cultivation and care methods are typical for ornamental geraniums: they prefer full sun to partial shade, well-drained soil, and regular, moderate watering. They are frost-tender in temperate climates and are typically grown as annuals or container plants, though they can be evergreen in milder districts. Propagation is commonly by cuttings, which roots easily in moist medium. Regular feeding, deadheading, and occasional pruning help maintain vigor and floral display. Zonale pelargoniums are valued for their reliability, variety of leaf patterns, and broad use in decorative gardening.
