Where Karl Foerster Feather Reed Grass thrives
Karl Foerster Feather Reed Grass is hardy across USDA zones 4 through 9. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 4–9 spans average winter lows from -30°F to 30°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 33 outright and splits 18 more down the middle — and which side of that line your land sits on changes the answer.
