Variety traits
Abundance and duration of flowering — Hydrangea macrophylla
Hydrangea macrophylla (Thunb.) Ser.
These traits characterize the potential for flower bud formation on terminal and lateral shoots, as well as the flowering interval, which depends on the cultivar's remontancy and overwintering conditions.
In the reference 59 varieties crop Bigleaf hydrangea, where this is mentioned in the description.
The abundance of flowering in Hydrangea macrophylla is determined by the cultivar's ability to set flower buds not only at the tips but also in leaf axils along the entire length of the stems, ensuring dense coverage of the shrub. The duration of flowering depends on the physiological characteristics of the cultivar and its remontancy, which allows for the formation of flowers on current-year growth in addition to last year's shoots.
Flowering performance is critically affected by cultural practices, particularly proper pruning, as most cultivars set buds on the previous year's wood. A lack of moisture and nutrients significantly reduces the duration of the ornamental period, and freezing of buds in harsh climates leads to a total loss of flowering without additional winter protection.
