Jonathan Green Black Beauty^® Ultra Grass Seed mixture combines our most elite Black Beauty® tall fescue seed varieties with our best Kentucky bluegrass to fill in bare spots quickly and invigorate worn-out lawns. Black Beauty® Ultra also contains premium perennial ryegrass for fast germination and wear tolerance in lawns that experience heavy traffic. The Black Beauty® Ultra seed grows naturally dark-green turf and is most similar to the Black Beauty® seed mixtures that sod growers purchase from us to grow high-quality sod within one year. This seed germinates in 7 – 14 days.
