Iowa is located in the Midwestern United States and is home to a diverse range of plant life. The state is divided into five distinct plant zones based on average yearly temperatures and precipitation. Each zone has its own unique set of plants suitable for growing in Iowa’s climate. Knowing which zone you live in can help you choose the right plants for your garden. So, what plant zone is Iowa in?Iowa is in Plant Hardiness Zone 4a to 5b.
Iowa Hardiness Zones
The United States Department of Agriculture (USDA) Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which plants are most likely to thrive in a specific location. Iowa has two hardiness zones, 5b and 6a. Zone 5b is the coldest part of the state and includes most of northern Iowa, while zone 6a covers most of southern Iowa. These zones are based on the average annual extreme minimum temperature for each area.
Gardeners living in zone 5b should expect cold winter temperatures that can dip as low as -15°F (-26°C). This zone covers Des Moines, Cedar Rapids, Sioux City, Dubuque, Waterloo, Mason City, Council Bluffs, Davenport, Ames and other areas in northern Iowa.
Zone 6a is slightly warmer than zone 5b and encompasses much of southern Iowa. Average winter temperatures range from -10°F to -5°F (-23°C to -21°C). This zone includes cities such as Ottumwa, Burlington, Muscatine and Marshalltown.
When choosing plants for your garden or landscape in Iowa it’s important to consider both USDA hardiness zones and microclimates. Microclimates are localized areas with different climatic conditions than the surrounding area due to factors such as elevation or proximity to bodies of water. While these local conditions can vary significantly from one location to another within a single hardiness zone they can have a major impact on what types of plants will succeed or fail in any given location.
How to Determine Your Plant Hardiness Zone
Determining your plant hardiness zone is essential for successful gardening. Knowing what plants are best suited for your climate will help you create a beautiful outdoor space. The USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which plants are most likely to thrive in a specific location. This map divides the United States into 11 hardiness zones based on average minimum winter temperatures. Each zone is further divided into “a” and “b” sections, with “a” being the colder section and “b” being the warmer section.
The USDA Plant Hardiness Zone Map takes into account many factors, such as average minimum winter temperatures, humidity, elevation, and proximity to bodies of water. It also considers factors like prevailing winds, snow cover, and soil types which may affect local temperatures. To determine your plant hardiness zone, simply enter your zip code into the USDA website or locate your region on the map itself. Once you have determined your zone, you can then select plants that are best suited for your climate.
When selecting plants for your garden or landscaping project, always consider their hardiness zones first. Plants must be able to survive in the climate they are planted in order to thrive. Many plants may not be well-suited to certain climates due to environmental factors like temperature fluctuations or lack of rainfall. It is important to select plants that can survive in the conditions that are present in your area in order to ensure success.
It is also important to note that even within each plant hardiness zone there can be microclimates which can affect how well a particular plant will grow. Although some plants may be suitable for an area based on its hardiness zone designation, it may not do well if planted in an area with a different microclimate than what it is used to.
By taking these factors into consideration when selecting plants for your garden or landscaping project, you can ensure success with whatever you choose! Knowing how to determine your plant hardiness zone is the first step towards creating a beautiful outdoor space that will last for years to come.

Plant Hardiness Zones in the United States
The Plant Hardiness Zones of the United States are divided into eleven zones. These zones are determined by average minimum temperatures, which are determined by the average coldest temperature during the winter months. The zones range from Zone 1, which is the coldest, to Zone 11, which is the warmest. Within each zone there is a range of temperatures that will determine what type of plants can be grown in that region. Knowing your zone can help you choose plants that will survive and thrive in your area.
The Plant Hardiness Zones were created by the United States Department of Agriculture (USDA) in order to provide gardeners with an easy way to determine what plants are suitable for their climate. The zones vary from state to state and even within states due to local conditions such as elevation or proximity to a body of water. It is important to note that while plants may not survive in one zone, they may thrive in another. Therefore it is important to research what plants have been proven to survive and thrive in your area before investing in them for your garden.
When choosing plants for your garden it is also important to consider other factors such as sunlight, moisture levels, soil type, and growing season length. Knowing your Plant Hardiness Zone will give you an idea of what plants will survive and thrive in your area but it is not a guarantee that they will all do well. Be sure to research each plant carefully before investing in it for your garden.
