Double-flowering — Pelargonium zonale

Pelargonium zonale (L.) L'Hér.

Double-flowering in Pelargonium zonale is a breeding trait characterized by an increase in the number of petals in a flower, which defines its ornamental form.

In the reference 162 varieties crop Horseshoe pelargonium, where this is mentioned in the description.

When evaluating double-flowering in Pelargonium zonale, a scale based on the number of petals per flower is used: single flowers have 5–6 petals, semi-double have 7–9, double have 10–14, and rosebud or densely double forms contain from 15 to more than 20 petals.

This trait directly influences flower typology, including groups such as rosebud types with petals curled in the center or carnation-flowered types with fringed edges. When propagated by cuttings, the double-flowering trait is stably transmitted to offspring, which allows for the maintenance of varietal purity in commercial cultivation.

In breeding, the goal is to combine double-flowering with high peduncle strength and petal retention, as densely double varieties possess increased aesthetic value for use in pot culture and landscape gardening.
