Will it survive your winters?
Hardiness zones show a normal bad winter. We check the worst one — Black Locust is hardy to about -40°F (estimated from USDA zone 3), so we'll score it against the real coldest nights your area has actually had.
Powered by ~35 years of daily lows from the nearest NOAA weather station. A risk read, not a guarantee — a sheltered spot or mature plant beats the odds.
