Supranova Poa Supina is the elite shade grass for dense shade in cool season areas. This is the best primo shade lawn grass on market today. It is specially designed for deep shade and little water although it has been used for golf courses, lawns, and athletic field turf for over 20 years. Supranova shade grass has been developed over the last 20 years and the breeding keeps improving. No other species outperforms this variety in the shade. It grows where no grass has grown before. Its wear tolerance and aggressive growth make it ideal for high maintenance and high wear areas. Supranova Poa supina produces the most shade tolerant, wear resistant, cool season grass on the market. Poa Supina is well adapted to cold temperatures. Unfortunately, the cost of grass seed for shade is quite high; therefore, the practicality of seeding mono-stands of the grass is often economically unfeasible. Evidence from Germany suggests relatively low rates (e.g., less than 10%) of Poa supina seed can be mixed with other cool season grasses and after several years of heavy traffic the stand will be predominantly Poa supina, providing superior coverage compared to stands without Poa supina. We have gone the extra mile to include 25% of Poa supina in our shade grass blend so you get faster results and better performance. We blend it with Rough Bluegrass which is also very shade tolerant. Rough Bluegrass thrives when cool, moist conditions prevail which is your typical Northern Climate shade. Rough Bluegrass seed produces a fine-textured turf grass and develops a high shoot density under cool, moist conditions. It is one of the most winter hardy turf grasses with very good low temperature tolerance. When you combine Rough Bluegrass and Poa supina into one blend, you get the absolute best grass seed for shade for cooler climates at an economical price.
