Variety description
10 August 2026
The variety is a compact cespitose plant, reaching a height of 30–60 cm with a bush width of up to 60–100 cm. The leaves are narrow, prone to drooping and curling, and have a characteristic variegated coloration: a cream-yellow central stripe and green margins. During the summer period, erect stems with yellow-green paniculate inflorescences are formed.
The plant is intended exclusively for decorative purposes and is suitable for container gardening, borders, and rock gardens. The variety prefers well-drained soils and bright locations or light partial shade. Frost resistance is limited to USDA zone 8; at temperatures below -7…-9°C, the plant requires protection.
