Abundance and Duration of Flowering — Petunia × hybrida

Petunia x hybrida hort. ex E. Vilm.

Key indicators of the ornamental quality of Petunia × hybrida, determined by the number of simultaneously open flowers on the plant and the total duration of continuous bud formation until the first frosts.

In the reference 6 varieties crop Garden petunia, where this is mentioned in the description.

The abundance of petunia flowering is assessed quantitatively by counting the buds on a single plant or visually by the degree to which flowers cover the vegetative mass. Highly ornamental varieties are characterized by the formation of 12–16 flowers or more, creating an effect of complete coverage of the plant with minimal foliage visibility.

The duration of flowering is recorded as the period from the opening of the first flower until the plant loses its ornamental appeal, reaching up to 90–100 days for F1 hybrids. Grandiflora groups are often inferior to Multiflora in terms of flowering stability under adverse weather conditions.

These indicators are influenced by light intensity, the regularity of fertilization, and the volume of the substrate, which should be at least 5 liters for trailing forms. An effective method for maintaining flowering is the removal of seed pods; however, hybrids with male sterility maintain their ornamental quality without this procedure.
