Petunia Double Flowering

Petunia Juss.

Double flowering in petunias manifests as the transformation of stamens into additional petals, resulting in semi-double and double flower forms.

In the reference 31 varieties crop Petunia, where this is mentioned in the description.

The classification of double flowering is based on visual assessment: semi-double forms have 1–2 rows of additional petals, whereas double forms exhibit pronounced deformation of the stamens. The stability of this trait is often limited, requiring vegetative propagation to preserve varietal properties, as the percentage of double-flowering plants can be unstable when propagated by seed.

Biologically, double-flowering petunias are characterized by a high degree of sterility due to the replacement of reproductive organs with petals and reduced growth vigor. Such plants are sensitive to weather conditions: large flowers are easily damaged by precipitation and are prone to rotting when exposed to moisture, thus requiring root irrigation and protection from wind.
