Variety description

10 August 2026

The variety is used primarily as a pot crop. In scientific literature, it is used to study the effect of nutrition regimes, including nitrogen and potassium concentrations, as well as types of substrate on plant growth and flower longevity.

The plant serves as a model object in genetic transformation experiments. Specific morphological traits, such as height, flower diameter, and flowering time, are not fixed and vary depending on growing conditions and applied agrotechnical practices.
