Variety description

10 August 2026

The variety is a mutant of Exacum affine. Due to the presence of semi-double flowers, the variety is propagated exclusively by vegetative means, through cuttings.

The plant has a compact habit: the bush height is 15–20 cm, and width is 10–15 cm. The leaves are glossy, heart-shaped with entire margins.

Flowering of the variety occurs from June to September. The plant is used as a pot culture for the home, as well as for placement in balcony boxes and hanging baskets.
