In which plant zones will hostas survive?
Hostas are hardy in U.S.D.A. Zones 3 to 9. That generally means hostas will grow from Canada to northern Florida. Hostas need to go dormant for at least 40 days where the temperature will remain near or drop to 40ยบ F. In northern climates, all hosta varieties will thrive. In the south, where the summer heat is more intense and lasts for longer periods of time, some varieties will not perform well, especially hostas with H. sieboldiana and H. ‘Tokudama’ in their parentage.
