Best Grass for Deep Shade: Supina Bluegrass and Alternative Groundcovers

Heavy shade, thin grass, can’t walk on it without damage. The answer is ‘Supina’ Kentucky bluegrass (Poa supina).

Why Supina

• Bred in Germany for ultra-low light.
• Outperforms all fine fescues in NTEP shade trials.
• Slow-growing = less mowing.
• Expensive, but worth it for the worst spots.

Where to Buy

Seedland.com (mail order) and some premium garden centers.

Practical Tips

• Sow thin—seedlings need space and light.
• Germination takes 2–3 weeks.
• Lay flagstones on regular paths to prevent wear.
• Deepest shade (under trunks): switch to hostas, pachysandra, ferns.

Supina is the only grass that truly thrives where others just survive. Blend it with cheaper fescues to stretch the budget.
