The plant reaches a height of 20–30 cm. The foliage is dark green, broadly ovate, with a serrated edge and pubescence. The capitulum inflorescences have a violet-blue or deep violet-purple shade; buds are also colored violet before opening.
The variety possesses resistance to heat and weather conditions. Due to its "self-cleaning" properties, new flowers conceal faded ones. It is distinguished by uniformity and stability of flowering. Used in containers, hanging baskets, and landscape compositions; sensitivity to fungal diseases is possible under conditions of excessive moisture.
