Variety description

10 August 2026

The bush reaches 1.5 meters in height and is intended for landscaping gardens, including semi-shaded areas. The flowers have soft shades, with the sepal coloration changing depending on soil composition: at a pH below 5.5, the flowers become bluish, and at a pH above 6.8 — pink, with possible greenish tones at the beginning of the flowering period.

The plant requires humus-rich, deep, and constantly moist soils. Mulching is recommended to protect the roots in cold climates. Maintenance involves removing faded inflorescences in the autumn and sanitary pruning at the end of winter; however, heavy pruning should be avoided, as it can lead to a lack of flowering in the following season.
