Double flowers in strawflower (Xerochrysum bracteatum)

Xerochrysum bracteatum (Vent.) Tzvelev

In strawflower, doubling is determined by an increase in the number and size of the dry involucral bracts, which partially or completely cover the central disk of the capitulum inflorescence.

In the reference 5 varieties crop Strawflower, where this is mentioned in the description.

The trait of double flowers in this crop is a breeding parameter that determines the ornamental quality and commercial value of the inflorescences. A high degree of doubling is characterized by a dense involucre that almost completely hides the central yellow disk, which contributes to better preservation of the marketable appearance in dried arrangements.

The evaluation of doubling during variety trials is carried out by experts based on the tightness of fit and the number of bracts. Varieties with pronounced doubling possess a more stable inflorescence structure and increased resistance to moisture during the growing process, which reduces the rate of production defects.
