Variety description

10 August 2026

The variety has a low-growth habit with fine leaf blades and a rich color ranging from medium-green to dark-green. It propagates by rhizomes, which contributes to the formation of a dense turf and good self-repair capability. The variety is the ancestor of a separate group of varieties known as "Shamrock-type".

The plant exhibits resistance to leaf spot, dollar spot, stripe smut, leaf rust, and powdery mildew, but is susceptible to damage by the meadow moth. Due to its high wear tolerance, the variety is actively used on sports facilities, golf courses, park areas, and in the production of sod.
