Double-flowering in Kalanchoe blossfeldiana

Kalanchoe blossfeldiana Poelln.

Double-flowering in Kalanchoe blossfeldiana is a varietal trait characterized by the presence of additional corolla lobes, giving the flower a rose-like appearance. This trait requires specific agronomic control due to the increased susceptibility of dense inflorescences to gray mold (Botrytis cine…

In the reference 77 varieties crop Flaming Katy, where this is mentioned in the description.

When evaluating double-flowering in Kalanchoe blossfeldiana, specialists use a qualitative description of the flower structure, observing the arrangement and number of corolla lobes on young buds. Unlike quantitative scales, variety trials employ descriptive categories such as 'fully double' or 'rose-like'. Breeding lines may be standardized by a minimum number of petals; however, there is no generally accepted scoring standard for this species.

The presence of double-flowering significantly affects the crop's agrotechnics. The increased mass of the flowers puts additional strain on the flower stalks, which necessitates plant shaping and the potential use of growth regulators. The dense structure of the inflorescences tends to retain moisture, which increases the risk of gray mold infection; therefore, maintaining ventilation and preventing water from getting onto the flowers is crucial during cultivation. At the same time, double-flowered varieties are distinguished by increased decorative longevity, maintaining their marketable appearance for up to 10 weeks.
