Gardening takes skill and finesse, especially when it comes to finding the best annuals to plant in Colorado. High-altitude gardening takes know-how and planning, in addition to the green thumb you need with gardening anywhere. Instead of hoping for the best, take the guesswork out of your annuals with this helpful guide to the right flowers for your mountain home.
Why Is Colorado So Challenging for Gardeners?
Colorado gets an average of 300 sunny days a year. That’s more than San Diego! But in the mountains, the sun is intense, making it hard to keep some flowering plants alive. The blooms can burn, and the flowers don’t thrive. Also, there is such a variety of moisture levels, wind exposure, and the risk of frost, even late in the summer, that it can be a challenge to choose the right flowers and plants for your garden at high altitude.
What Are the Best Annuals to Plant in Colorado Mountains?
Some of the most reliable and best annuals to plant in Colorado mountain gardens include marigolds, zinnia, and sunflowers. They can stand up to the heat and intensity of the sun. Other options are Dahlia, snapdragons, pansies, petunias, and verbena. Though the nights in the Rocky Mountains can get quite cool, even in the summer, it can add to the intensity of the color of these flowers.
When Is the Best Time to Plant Annuals?
The best annuals to plant in Colorado can’t be planted until after the last frost, which is often thought to be after Memorial Day. To get flowers that will give your garden color right away, plant those that are already in full bloom. This will allow you to take advantage of the entire season.
Something else to keep in mind is when each of your chosen annuals will be in bloom. If you want color throughout the summer and into fall, it’s a good idea to plan for planting a variety of plants at different times throughout the season. Consider adding perennials to the garden to ensure color and scent that returns each year. Ornamental grasses can be hardy in the altitude and climate of the mountains, and can be a great accent to the flowers that bloom in your annual garden.
Other Considerations to Help Make Your Garden Grow
Colorado is a dry climate. If you’re planting annuals, keep in mind they aren’t generally drought resistant. It’s important to make sure your garden gets ample water and moisture to keep your flowers and plants thriving throughout the summer. Proper drainage is also key to good moisture balance.
