Variety description

10 August 2026

The shrub has a dense, well-branched habit. Strong stems support heavy conical inflorescences without lodging. The plant reaches about 80 cm in height and width, in some cases up to 1 meter.

Flowering lasts from July to September. The color of the flowers changes sequentially from lime-white to green, and then to pink. The variety is distinguished by an increased number of formed inflorescences.

The plant has frost resistance down to -30 °C. Due to its compact size, the variety is suitable for container cultivation, as well as for creating borders and group plantings in small gardens.
