Will Agastache freeze?

Question

I have 83 Agastache I planted last year. In the next few days, the temperature could go below 32 degrees. Can they survive a short freeze? Talking hours – or will they need to be covered??

Answer 1

Your plants should be just fine in temperatures at or below freezing.

Agasthache are hardy down to 10 degrees F.
