Iowa’s Climate and Benefits to Native Plants

Iowa has a standard, four-season climate. This is mostly due to the state’s middle position within the continent itself. The winters are cold and dry, with lots of wind and the summers are long, warm, and humid. While the state does get some snow in winter, it’s usually lighter than the amount in states more to the north and east of Iowa.

Because of this, it hosts a variety of native plants and wildlife. Agriculture has pushed out much of the state’s native prairie and wetland vegetation, but these species can still thrive in a controlled environment, such as a garden or landscape.

Naturally, the woodlands areas thrive along rivers and hill parts of the state where you will find ash, elm, and hickory trees to name a few. Understanding the zone and climate where you live will help you choose flowers that do the best, require the least amount of upkeep, and bloom longer and more beautiful for you to enjoy.
