Variety traits
Petunia x hybrida hort. ex E. Vilm.
A critical morphological characteristic of petunia that determines plant architecture and its landscape application options. This trait varies significantly from 12 to 70 cm and more, depending on varietal characteristics and growing conditions.
In the reference 6 varieties crop Garden petunia, where this is mentioned in the description.
Petunia plant height measurements are conducted during the peak flowering period from the substrate surface to the highest point of the plant. To obtain representative data, readings are recorded for at least five typical specimens within a plot, calculating the mean value for the cultivar.
Petunia cultivars are classified into groups by height: low dwarf forms reach 12–25 cm, medium forms 20–50 cm, and tall forms 60–70 cm or more. In trailing (ampelous) varieties, the height of the central plant differs significantly from the length of the shoots, which may exceed one meter.
Plant height directly influences agrotechnical decisions: compact forms are preferred for borders, whereas robust cultivars require larger volumes of soil. Pinching is used to control vertical growth and stimulate branching, and the high wind resistance of tall plants is taken into account when choosing a planting site to prevent lodging.
