Abundance and duration of flowering of Bidens ferulifolia

The flowering abundance of Bidens ferulifolia is defined as the plant's ability to form a dense mass of inflorescences, creating a solid floral cover. The flowering duration spans from the beginning of summer until the arrival of the first frosts, with the plant capable of blooming almost continuously under favorable conditions.

Key agrotechnical factors for regulation include the light regime, requiring at least 5–8 hours of direct sunlight, and the regular removal of wilted inflorescences to stimulate new buds. Nutritional balance is critical: an excess of nitrogen promotes foliage growth at the expense of flowering, while the selection of seedless varieties allows for the extension of the flowering life cycle by preventing seed formation.
