Double-floweredness in Pelargonium (hybrids)
hybrids between Pelargonium peltatum and Pelargonium zonale
Double-floweredness in Pelargonium hybrids is a qualitative morphological trait classified based on the number of petals per flower according to UPOV standards.
In the reference 25 varieties crop Ivy-leaved geranium, where this is mentioned in the description.
According to international Distinctness, Uniformity, and Stability (DUS) testing standards, Pelargonium double-floweredness is determined by the flower type. Single flowers have up to 5 petals, semi-double flowers have 6 to 9, and double flowers include 10 or more petals. The rosebud form is distinguished separately, characterized by high density and a specific arrangement of petals that prevents the bud from opening fully.
The expression of this trait significantly influences agrotechnics and the ornamental qualities of the plants. Varieties with single flowers possess better self-cleaning ability and resistance to precipitation. Double-flowered forms require more meticulous care, including the regular removal of spent inflorescences to prevent gray mold, as the dense structure of the inflorescence retains moisture and impedes aeration.
