Ask any recent newcomer to Colorado how it went when they tried to transplant their favorite flowers from back home. Colorado gardeners have learned to identify and adapt to the unique, varied climate conditions and growing seasons we find here in Colorado. Our hot summer days with intense high altitude sunlight and drying winds, combined with cool nights, can work to the gardener's advantage with proper planning. At O'Toole's Garden Centers we have 37 years of experience identifying the annuals that are perfectly suited for Colorado that will provide a dynamic blast of color to your garden this year. Here are just a few of the hundreds of annuals we carry at all three of our locations.

Marigolds are considered as among the easiest and most versatile flowers to grow in a garden because they tolerate most soils. In temperate climates, seeds are sown in spring for blooms that last through the summer and into the fall. One of the most popular and easiest to grow annuals, Marigolds add a bright splash of yellow, orange or red to the garden. These natives of Mexico and Central America love the sun and are drought tolerant.
