Last Frost Date

In Zone 1b the average date of last frost happens on June 15. It might get as low as -55°F during the coldest months of winter.

Just be sure to remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 1b and it can change quite a bit from year to year. Since half of the time in Zone 1b we get surprised by a frost after June 15 be ready to cover your gomphrena if we have one of those late frosts.
