Northern Illinois is in Hardiness zone 5, and southern Illinois is in zone 6 except for the far south, which is zone 7. Illinois is colder in the north and warmer in the south, and this affects the hummingbird plants that survive in each area. Plants thrive in different zones and can tolerate minimum temperatures but not survive if too cold. The USDA plant hardiness zone map splits the United States into 13 zones based on the average minimum temperature, and within a state, there will also be different zones.
