Reinders - Poa Supina Shade Seed - 1 LB Bag

Reinders Poa Supina Shade Seed offers unmatched shade performance for turf areas that remain moist and receive minimal sunlight. Native to alpine regions and widely used across Europe, Poa supina thrives in shaded and compacted soils where other turf types fail. It is ideal for use on golf course approaches, shaded lawns, high-wear athletic field zones, and beneath trees where dense canopies limit light.

This perennial cool-season grass spreads aggressively through stolons, forming a dense, uniform surface that tolerates heavy foot traffic. Its superior cold tolerance allows it to green up earlier than most other turfgrasses. While supina struggles in dry or hot climates, it excels in northern and cool-season environments, particularly in areas with adequate moisture and fertility.

Key Features & Benefits:

• Thrives in 90% shade—ideal for under trees, between buildings, or moist shaded sites
• Spreads via stolons for fast coverage and self-repair in compacted or high-traffic zones
• Greens up early in spring; excellent cold and wear tolerance
• Compatible with Kentucky bluegrass and perennial ryegrass in shade seed mixes
• Lower risk of weed invasion due to aggressive growth habit
