Variety description

10 August 2026

The plant forms a neat, rounded bush 30–45 cm tall with dense dark green foliage. The lemon-yellow flowers are daisy-shaped. The variety is practically sterile, which ensures long-lasting flowering from late June until frost without the need for deadheading.

The plant possesses high resistance to powdery mildew and leaf spot, and is adapted to hot climates and drought. Winter hardiness corresponds to USDA zone 5. The variety is suitable for container cultivation, creating borders, and mass plantings.
