Plant height — Petunia × hybrida

Petunia x hybrida hort. ex E. Vilm.

An important morphological indicator that determines the habit and ornamental qualities of a cultivar. It is measured as the distance from the substrate to the highest point of the plant and is used in DUS testing.

In the reference 5 varieties crop Garden petunia, where this is mentioned in the description.

For Petunia × hybrida, plant height is measured from the soil surface to the highest point of the stem. This parameter is a mandatory (asterisk) characteristic in DUS test protocols. Depending on the cultivar group, the values vary significantly: compact forms of the Multiflora and Milliflora groups usually reach 20–30 cm, while large-flowered varieties of the Grandiflora group can grow up to 50–70 cm or more.

The height trait directly influences cultivation techniques and the use of the crop. Varieties with significant height require regular pinching to prevent stretching, and a lack of light leads to etiolation and excessive internode elongation. The choice of cultivar by height determines its place in landscape design: compact forms are suitable for borders and the foreground, while taller ones are intended for the background and accent compositions in containers.
