Variety description
10 August 2026
The plant forms a dense, profusely branched bush 46–56 cm high and 81–91 cm wide. The leaves are narrow, thread-like, dark green in summer, and turn bright yellow-orange in autumn. The flowers are light periwinkle-blue, star-shaped, and gathered in inflorescences. Flowering occurs from late spring to early summer.
The variety is resistant to chlorosis, heat, and humidity, as well as deer browsing. Winter hardiness corresponds to USDA zones 4–9. Once established, it shows moderate drought tolerance. To maintain a dense bush structure and prevent sprawling, it is recommended to prune the stems by 15–20 cm after flowering.
