Identifying Denver’s Plant Hardiness Zone
Denver is located in the Rocky Mountain region of the United States, making it a unique area for gardening and landscaping. The area has a variety of climate zones, including humid subtropical, arid desert and temperate climates. When it comes to gardening, one of the most important factors to consider is the plant hardiness zone. This will help gardeners determine what types of plants are best suited for their region.
The United States Department of Agriculture (USDA) outlines plant hardiness zones across the country, using average annual minimum temperatures as a basis for categorization. Denver is located in zone 5a on this scale, which means that the average minimum temperature in winter is -20 to -15°F (-28.9 to -26.1°C). Plants that are recommended for this zone include many shrubs and trees such as boxwood, cherry laurel, evergreens, magnolias and spireas. It should be noted that these plants may not thrive if exposed to extreme cold temperatures outside of their hardiness zones.
Gardeners in Denver should also be aware that there are microclimates within their area that could affect what types of plants do best in their gardens. For instance, there may be areas with more sun exposure or higher elevation which could affect the success or failure of certain plants. It is important to research each individual plant before deciding where to place it in order to ensure success with your garden planting efforts.
Knowing your plant hardiness zone is a key factor when planning your garden or landscape project in Denver. Although some experimentation may be required to determine what works best in your specific environment, understanding this basic information can help you select the right types of plants for your climate and provide you with beautiful results!

Denver Plant Hardiness Zone Map
The United States Department of Agriculture (USDA) has developed a Plant Hardiness Zone Map for Denver, Colorado. This map provides gardeners and landscapers with information about the type of plants that can be grown in the area, as well as the approximate dates for planting and harvesting. The map divides the city into 10 hardiness zones, which range from Zone 4a to Zone 8b. Each zone denotes a range of average low temperatures for each month of the year, allowing gardeners to select plants that are well-suited to their climate.
Zone 4a has an average low temperature of -20 degrees Fahrenheit, making it one of the coldest zones in Denver. This zone is home to many winter-hardy trees and shrubs such as red maple, white fir, and northern red oak. Gardeners in this zone should plan on planting cold-tolerant crops such as kale, potatoes, and spinach in late spring or early summer.
Zone 8b is one of the warmest zones in Denver, with an average low temperature of 10 degrees Fahrenheit. This zone is ideal for growing many warm-weather plants such as tomatoes, peppers, squash, melons, beans, and cucumbers. Gardeners in this zone should plan on planting these crops between late spring and early fall for optimal growth.
By consulting the USDA Plant Hardiness Zone Map for Denver gardeners can make informed decisions about what plants to grow in their area based on their climate conditions. With this information they can choose plants that will thrive in their local environment and ensure that their gardens are successful from season to season.
Factors that Determine Plant Hardiness Zones in Denver
Denver, Colorado is located in USDA Plant Hardiness Zone 5b. The hardiness zone of a particular area is determined by a combination of several factors, including average annual extreme minimum temperatures, elevation, and local microclimates.
The average annual extreme minimum temperature in Denver is -12°C (10°F). This determines the hardiness zone of the area, as colder climates are designated with lower numbers. For example, Zone 1 has an average extreme minimum temperature of -50°C (-58°F) or colder, while Zone 10 has an average extreme minimum temperature of +1°C (+34°F) or warmer.
Denver’s elevation also contributes to its hardiness zone designation. At an elevation of 1610 meters (5,280 feet) above sea level, Denver’s climate is significantly cooler than lower-elevation areas like Boulder and Fort Collins. This difference can be seen in the hardiness zones for each area; while Denver is located in Zone 5b with an average extreme minimum temperature of -12°C (10°F), Boulder and Fort Collins are both located in Zone 6a with an average extreme minimum temperature of -17°C (1°F).
Finally, local microclimates can affect a region’s hardiness zone designation. Microclimates are small areas within a larger region that may have significantly different weather patterns due to variations in terrain or other features like bodies of water. For example, Denver’s Stapleton neighborhood may have a slightly warmer climate due to its location near Lowry Air Force Base and Sand Creek Park. As a result, Stapleton could be designated as Zone 6a instead of Zone 5b like the rest of Denver.
Overall, Denver’s hardiness zone is determined by factors such as average annual extreme minimum temperatures, elevation, and local microclimates. Understanding these factors can help gardeners choose plants that are suitable for their climate and ensure that their gardens thrive year-round.
