The three cultivars of Perennial Rye-grass in this seed mix ensure rapid germination and establishment. The smooth stalked meadow grass cultivars are then able to spread through the sward due to their networks of creeping rhizomes. This ensures exceptional wear tolerance, high shoot density and good recovery abilites.
