Vigor — Hydrangea macrophylla
Hydrangea macrophylla (Thunb.) Ser.
A qualitative characteristic of the development rate of the plant's aerial part, which determines the intensity of the shrub's decorative volume formation and the required maintenance.
In the reference 29 varieties crop Bigleaf hydrangea, where this is mentioned in the description.
The vigor of Hydrangea macrophylla is typically described as moderate, medium, or restrained. The development intensity is often assessed by the annual shoot growth, which can range from 20–30 cm per year. High growth rates contribute to the rapid formation of the plant's habit but require regular pruning to control size and prevent excessive crown density.
This trait directly influences agrotechnical decisions: cultivars with restrained growth are preferable for container cultivation, as they populate the limited substrate volume more slowly. When planning plantings, vigor determines the spacing between plants based on the projected height and crown diameter. The crop's growth energy is significantly influenced by nutrition conditions, moisture regime, and soil pH levels, which affect nutrient availability.
