Double-flowering in Garden Chrysanthemum

Chrysanthemum x morifolium Ramat.

Double-flowering in garden chrysanthemum is defined as a morphological trait of inflorescence structure, determined by the ratio of ray to disc florets.

In the reference 60 varieties crop Florist's daisy, where this is mentioned in the description.

The double-flowering trait is assessed through the typology of the capitulum inflorescence structure. Non-double (single) inflorescences are characterized by a large disc of tubular florets and a small number of ray floret rows; semi-double forms have at least five rows of ray florets while maintaining a visible disc; and fully double forms are those where the disc is practically absent due to the transformation of tubular florets into ray florets.

The degree of double-flowering is a key characteristic of cultivar marketability, determining its market segment, particularly for single-stem cut flowers. From a biological perspective, a high degree of double-flowering often correlates with sterility of ray florets, which limits seed propagation and necessitates the use of vegetative methods. Under open-field conditions, dense double inflorescences are prone to rotting during periods of excessive moisture due to water accumulation between the petals.
