Variety description

10 August 2026

The variety belongs to the Lake series and is intended for use as a "filler" in floral arrangements. The time from sowing to flowering when grown in the spring period is approximately 169 days. The plant reaches a height of 76–107 cm and requires stem support with netting or stakes.

Inflorescences are dense, corymbose, and dark purple in color. The crop is sensitive to soil waterlogging, which causes the development of root rots. To initiate flowering, the plant requires a photoperiod of 16 hours; it is cultivated primarily as an annual.
