Flower color — Begonia elatior

Begonia x hiemalis Fotsch

Flower color is a key varietal trait of Begonia elatior, evaluated according to UPOV standards and defining the plant's ornamental value.

In the reference 14 varieties crop Elatior Begonia, where this is mentioned in the description.

During variety trials and seed production, the flower color of Begonia elatior is classified using visual scales as a qualitative trait, which includes the primary color and additional elements such as margins or spots. For scientific purposes, instrumental assessment methods using Lab color space coordinates can be applied.

The expression of this trait is influenced by growing conditions. Increased pigment saturation is achieved by lowering the temperature to +15…+17 °C during the final stages of development, while insufficient light or extended day length often lead to the lightening of flowers and a decrease in their intensity.

Color stability depends on the genetic characteristics of the cultivar and the method of propagation. Commercial vegetative propagation via cuttings is preferable to generative methods, as it better minimizes trait variability and the emergence of undesirable deviations, such as stripes or shifts in the original hue.
