Variety description

10 August 2026

The variety forms a dense stand, which helps suppress the spread of Poa annua. The plant has a bright dark green color, which it maintains both in summer heat and during the winter period.

The variety demonstrates resistance to dollar spot, brown patch, and copper spot, as well as to root rot and pink snow mold. It requires intensive professional care, including regular mowing, verticutting, topdressing, and thatch control.

Designed for creating high-quality playing surfaces (putting greens). Used both independently and as part of specialized grass mixtures.
