Variety description

10 August 2026

The variety is a compact shrub with a dense crown 60 to 90 cm in height and width. The plant's leaves are dark green and glossy, and flowers of a saturated dark blue or blue-violet color are collected in axillary and terminal corymbs.

The plant belongs to late-flowering varieties, with the flowering period covering late summer and autumn. The crop is drought-tolerant, heat-resistant, and adapted to hardiness zones 5–9, although in cold regions the above-ground part may die back to ground level with subsequent regrowth in spring.

The variety prefers sites with full sun exposure and well-drained soils. To maintain shape and stimulate growth, spring pruning is recommended. The plant attracts pollinators and is used in border plantings, flower beds, and container gardening.
