Variety traits
Petunia x hybrida hort. ex E. Vilm.
Corolla diameter is a key morphological trait of petunia that determines its classification into garden groups such as Milliflora, Multiflora, or Grandiflora, and influences the choice of growing conditions.
In the reference 4 varieties crop Garden petunia, where this is mentioned in the description.
During variety trials, flower diameter is measured at the mass flowering stage across the widest part of the open corolla in centimeters. Flower sizes are closely linked to garden group classification: from 2–4 cm in Milliflora and 4–7 cm in Multiflora to 8–16 cm in the Grandiflora group.
The flower diameter trait has an inverse relationship with flowering abundance: small-flowered groups form a greater number of buds, creating a solid carpet effect. Large-flowered forms, while highly ornamental, are more sensitive to precipitation and wind, making them better suited for containers and sheltered locations.
