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 twenty 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. It’s wear tolerance and aggressive growth make it ideal high maintenance and high wear areas. Today Supranova Poa supina shade grass seed produces the most shade tolerant, wear resistant, cool season grass on the market.
Poa Supina is well adapted to cold temperatures and is found commonly in the sub-alpine regions of the German and Austrian Alps. In Germany, the common name is Lägerrispe, which means, "where the cows lay". The name is a reflection of the ability of Poa supina to persist and even thrive on cattle trails, even in shaded woodland areas. Another attractive asset is the apparent resistance of Poa supina to many diseases which results in fewer fungicide applications. 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 mix so you get faster results and better performance. We mix it with Poa Trivialis which is also very shade tolerant. CPoa Trivialis thrives when cool, moist conditions prevail which is your typical Northern Climate shade. Poa Trivialis seed produces a fine-textured turf grass and develops a high shoot density under cool, moist conditions. It is capable of withstanding a considerable amount of shade. It is one of the most winter hardy turf grasses with very good low temperature tolerance. When you combine Creeping Fescue and Poa supina into one mix, you get the absolute best grass seed for shade for cooler climates at an economical price.
This mixture approximately contains the following:
- 25% Supranova Poa Supina Bluegrass
- 75% Poa Trivialis

True Putt is an excellent new perennial bluegrass that is medium green depending on fertility and forms a uniform, dense turf at greens height. This creeping bluegrass is medium to fine textured and forms an extremely dense putting green grass surface. True Putt helps crowd out Poa annua better than creeping bentgrass. This Bluegrass seed germinates rapidly in 5 to 7 days under optimum conditions especially when kept continually moist. It is very vigorous and mixes well with creeping bent grass in a 50/50 mixture. True Putt is a great grass seed choice for the home golf green.
True-putt is drought and shade tolerant and recovers well after water stress events. Tolerates close mowing to 1/8 inch (optimum mowing height on greens is 5/32), but will also perform well at 1/2 inch mowing height. Creeping bluegrass is a deep rooted grass which has exhibited some field resistance to pink snowmold. This putting green grass is well adapted to the cool, moist climate especially in the northern half of the United States.
True-Putt will soon be one of the leading putting green grass varieties on the market. A creeping bluegrass putting green has excellent density, shade tolerance, heat tolerance, wear tolerance, and cold tolerance. True Putt golf grass establishes quickly from grass seed, and it produces a thick turf competing with the grassy weed Poa annua. For those of you who want to build your own putting green, True Putt is a great choice for putting green seed.
