Variety traits
Saintpaulia ionantha H. Wendl.
Saintpaulia double flowering is a qualitative characteristic of flower shape determined by the number of petals in the corolla. This trait classifies varieties into single, crested, semi-double, and double.
In the reference 31 varieties crop African violet, where this is mentioned in the description.
There are four categories of double flowering expression for Saintpaulia. Single flowers have a standard five-petal corolla. Crested flowers are defined by the presence of 1–3 additional underdeveloped petals in the center. Semi-double flowers contain from 6 to 9 petals, while double flowers include 10 or more petals.
In breeding, double flowering is considered a dominant trait; however, its inheritance often depends on the genotype of specific parent pairs. The stability of trait expression is influenced by environmental conditions, such as lighting and temperature; when agrotechnical practices are compromised, some varieties exhibit a simplification of flower shape.
