Abundance and duration of flowering in Kalanchoe blossfeldiana

Kalanchoe blossfeldiana Poelln.

Key quality indicators for a cultivar, measured by the number of flower stalks and days of decorative effect. The typical duration is 6–8 weeks, reaching up to 11.5 weeks in double-flowered forms.

In the reference 12 varieties crop Flaming Katy, where this is mentioned in the description.

The flowering duration of Kalanchoe blossfeldiana is recorded in days from the opening of the first flowers until the end of the decorative period, averaging 6–8 weeks for standard cultivars and up to 11.5 weeks for the Kalandiva series. Abundance is assessed by the number of flower stalks and flowers forming dense cymes.

Kalanchoe is an obligate short-day species; therefore, the abundance and timing of bud initiation are strictly dependent on the light regime, including the use of artificial shading. To ensure a decorative floral "cap" effect in commercial cultivation, growth retardants are applied.
