In the reference 5 varieties crop English lavender, where this is mentioned in the description.

The flowering duration of Lavandula angustifolia is recorded as the period in calendar days from the opening of the first flowers to its completion. On average, for the species, this period is 25–30 days, although the ability to re-bloom after pruning significantly extends the ornamental period.

Flowering abundance does not have a strict metrological expression and is determined expertly through correlation with inflorescence density, the number of whorls, the length of flower stalks, and the total yield of raw material. High levels of abundance are characterized by the uniform coverage of the bush with dense inflorescences.

In industrial cultivation, these traits are key for determining harvest timing aimed at essential oil production. In landscape use, the abundance and duration of flowering serve as the primary criteria for the aesthetic value of a cultivar.
