Abundance and duration of flowering — Regal pelargonium

Pelargonium grandiflorum (Andrews) Willd.

For Regal pelargonium, flowering performance depends on the completion of a mandatory winter cooling period and the light regime, which determine floral bud initiation.

In the reference 10 varieties crop Regal pelargonium, where this is mentioned in the description.

The assessment of flowering abundance and duration in Regal pelargonium is based on recording the number of peduncles and flowers per inflorescence, as well as the time interval from the onset to the completion of mass flowering. Unlike other species, this type is characterized by a limited flowering period, lasting approximately 4–8 weeks during the spring-summer season.

A key factor in ensuring abundant flowering is maintaining the plant in a state of cold dormancy at temperatures of +5…+12°C for 6–8 weeks before the start of vegetation. Violation of the temperature regime (exceeding +25°C), insufficient light, or untimely pruning that leads to the removal of initiated flower buds directly reduces these ornamental performance indicators.
