Flower diameter — Pelargonium zonale

Pelargonium zonale (L.) L'Hér.

An important morphological trait of Pelargonium zonale used for cultivar evaluation and breeding, defined as the diameter of an individual flower when the petals are spread horizontally.

In the reference 6 varieties crop Horseshoe pelargonium, where this is mentioned in the description.

According to the UPOV guidelines for Pelargonium zonale, the measurement of the flower diameter is conducted after positioning the petals horizontally. In breeding, this parameter is evaluated in combination with peduncle strength, as large flowers form massive inflorescences that require a stable stem structure to maintain ornamental value.

Flower size is classified into groups: miniature, standard, and large. The actual value of the trait is subject to variability under the influence of environmental conditions, including light intensity, mineral nutrition, and container volume. Additionally, flower size may depend on their density within a single inflorescence.
