Variety traits

Hydrangea Inflorescence

Hydrangea L.

The hydrangea inflorescence is a key morphological trait classified by shape, the ratio of fertile to sterile florets, and linear dimensions.

In the reference 87 varieties crop Hydrangea, where this is mentioned in the description.

In hydrangea variety trials, inflorescences are evaluated by shape, such as conical, globose, or corymbose, as well as by types depending on the distribution of fertile and sterile florets. For Hydrangea macrophylla, globose inflorescences with a diameter of 20–25 cm are considered the standard, while for Hydrangea paniculata, panicles with a length of 30 cm or more are used.

Large inflorescences require high shoot strength to prevent lodging under their own weight. The size and quality of inflorescences depend on the pruning intensity, plant age, and environmental conditions: specifically, in many species, inflorescence coloration is influenced by soil acidity levels and aluminum availability.
