Variety traits

Plant height — Petunia × hybrida

Petunia x atkinsiana D. Don

Plant height in Petunia × hybrida is a key morphological trait that determines the choice of agrotechnology, planting density, and the ornamental use of a cultivar.

In the reference 7 varieties crop Garden petunia, where this is mentioned in the description.

Height is measured from the soil surface to the top of the plant or the highest point of the canopy. For trailing forms, this metric is less significant than shoot length, which can reach 1.5–2 m, whereas for bush forms, the height varies from compact 10–20 cm to tall 40–80 cm.

When evaluating habit, artificial stretching of shoots is not permitted in order to maintain data accuracy. The trait is genetically inherited and subject to the influence of heterosis, which is taken into account when creating F1 hybrids to ensure uniform marketability in greenhouse production and resistance to lodging in open-field cultivation.
