Variety traits
Exacum L.
The plant height of Exacum is a defining morphological trait that characterizes the plant habit and varies depending on varietal characteristics within the range of 10–30 cm.
In the reference 4 varieties crop Persian violet, where this is mentioned in the description.
The typical plant height of Exacum affine ranges from 10 to 30 cm. Short dwarf forms, such as 'Midget' or 'Romeo', reach 10–15 cm, making them suitable for small containers. Standard breeding forms are capable of reaching the upper limit of the 30 cm range.
This trait is used for the evaluation of varieties within the framework of UPOV and CPVO guidelines during variety testing. Measurements are taken on adult specimens in the flowering phase. The genetically determined compactness of the plant directly determines the choice of pot size and the need for habit shaping.
To maintain ornamental appeal and prevent shoot lodging under low-light conditions, breeding is aimed at creating varieties with shortened internodes. This allows for maintaining a dense, spherical plant shape, reducing the need for staking or the use of growth regulators.
