The variety is a tetraploid form of perennial ryegrass. The seeds of this variety have increased weight, which promotes rapid rooting and the emergence of strong seedlings. The plant forms a less dense stand with a wide leaf blade.
The variety possesses complex resistance to diseases, including rust, Fusarium, leaf spot, and red thread, as well as increased tolerance to soil salinity. It is used primarily as a component of grass mixtures for lawns and sports surfaces, improving the development of associated grass species.
