Variety traits
Hydrangea macrophylla (Thunb.) Ser.
A qualitative indicator of bush architecture that determines its density, flowering potential, and cutting yield. It is visually assessed as the plant's ability to autonomously form shoots or branch intensively following agrotechnical treatments.
In the reference 12 varieties crop Bigleaf hydrangea, where this is mentioned in the description.
For Hydrangea macrophylla, branching is a key habit characteristic affecting the plant's commercial appearance and ornamental value. High branching ensures bush density and uniform inflorescence distribution, which is critical for potted crops, where the number of flower buds is directly linked to flowering quality.
This trait lacks rigid measurable standards and is expert-assessed as the cultivar's ability to form a compact structure without additional interventions. In commercial production, branching intensity also determines the propagation rate, as the yield of planting material depends on the development of lateral shoots.
Branching in this crop is a manageable trait. To correct bush architecture and stimulate lateral branch development, pruning, pinching, or the use of growth regulators are applied, allowing for the desired canopy density to be achieved depending on cultivar-specific characteristics.
