Do they tolerate really cold weather or freezing temps? How about really hot days, like in the 90's? I live on Washington state and we get all kinds of climates so I'm not sure where to plant my hostas. Thank you!
Climate for Hostas
Some varieties of hosta are rated for zone 3. More varieties survive zone 4 winters. The plants die back to the crown (goes dormant) after frost as a way of surviving winter. Winter mulch lessens the risk of heaving. Hosta do not tolerate drought without watering and most varieties don't do well in full sun. In general, cold winters and warm summers are favored by hosta.
