Abundance and duration of Dahlia flowering

Dahlia Cav.

These traits are evaluated using expert scoring methods due to the lack of uniform variety testing standards. The flowering period of the crop ranges from mid-summer to the first frosts and depends on the biological characteristics of the variety and growing conditions.

In the reference 51 varieties crop Dahlia, where this is mentioned in the description.

There is no unified state methodology for evaluating the abundance and duration of Dahlia flowering. Researchers apply their own scoring scales based on phenological observations of the start and end dates of mass flowering, or evaluate ornamental value as a combination of several criteria.

Biologically, the flowering of the crop is closely linked to varietal characteristics: dwarf small-flowered Dahlias usually bloom earlier, while large-flowered tall forms enter the flowering phase later. The overall flowering duration depends on agrotechnical practices, temperature regime, and photoperiod.

Extremely high temperatures can accelerate the rate of flower development, yet often lead to a shortening of the total flowering period or bud abortion. The practical value of a variety for landscaping and cut flower production is determined by its ability to maintain ornamental quality for as long as possible throughout the growing season.
