If you are planning on gardening in Denver, Colorado, it is important to know your planting zone. The United States Department of Agriculture (USDA) has divided the country into 11 different planting zones based on the average minimum temperatures of each region. These zones help gardeners determine which plants are likely to thrive in their area.
Denver’s Planting Zone
Denver, Colorado falls into planting zone 5b. This means that the average minimum temperature in Denver is between -15 to -10 degrees Fahrenheit. When choosing plants for your garden, it is important to choose ones that can withstand these colder temperatures.
What Plants Grow Well in Zone 5b?
Some plants that grow well in planting zone 5b include perennials such as black-eyed susans, daylilies, and sedum. These plants are able to withstand the colder temperatures and will come back year after year. Other plants such as tulips, daffodils, and crocuses are also able to thrive in zone 5b.
