Latest IA growing zone mapThe growing zone is a measure of the lowest temperature that a plant can survive based on average lowest year temperatures, helping you to decide what plants would grow best in your particular climate. Since Cedar Rapids is in growing zone 5a this means that plants there can survive temperatures as low as -20 to -15 degrees Fahrenheit. Plants for Cedar Rapids's climate should be chosen with this in mind, or plants should be moved inside to keep their core temperature in the right range if necessary.
Some zones may have been changed by the USDA as of 2023. To see if the Cedar Rapids area has been affected, refer to this map of half zone changes from the 2012 version of the USDA zones to the 2023 version.
Half zone changes from 2012 to 2023The updated map shows that over half of the Southeast has warmed by about half a zone. For gardeners, that means you can now grow plants that tolerate a bit more heat and less frost than before. The tan areas reflect this shift. Meanwhile, the white areas had slight temperature changes, but not enough to move them into a new zone. In the Western U.S., a few spots shifted cooler. That’s not due to a colder climate, but because the new map uses a larger dataset, giving a more accurate picture of local conditions. It's important to keep track of these changes when planning your garden!
