Variety description
10 August 2026
The plant forms a dense, compact clump 17–28 cm high and up to 50 cm wide. The leaves are fleshy, glossy, yellowish-green with a purple-brown tint and a red margin, darkening throughout the season.
Large corymbose inflorescences reach 12–20 cm in diameter. Dense grayish-green or white buds open into small star-shaped flowers of a deep pink-purple shade. Flowering begins in late summer and continues until autumn.
The variety has strong stems and high resistance to lodging. Once established, the plant tolerates heat and drought well and demonstrates resistance to diseases. It retains its decorative qualities during the winter period and is suitable for cutting.
