Variety description

10 August 2026

The plant is a low-growing variety with dark green, fine-textured leaves, forming a dense and uniform turf. The variety is characterized by high germination vigor, rapid establishment, and good winter hardiness. It is optimally adapted to moist, poorly drained soils with a pH level of 6 to 7.

The variety possesses pronounced shade tolerance, the ability to retain color during the cold period, and increased resistance to dollar spot, rust, and leaf spot. It is specifically developed for winter overseeding into bermudagrass in southern regions, ensuring a uniform spring transition, and is also suitable for use in shaded areas in northern latitudes.
