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.

Available in nearly every color under the sun, also called Million Bells, calibrachoa is a modern garden essential. Calibrachoa blooms with hundreds of miniature petunia-like flowers, forming a blanket of brilliant color from summer to early fall. Calibrachoa also drops its spent flower heads, so you don’t need to deadhead. Though it creates a dramatic effect anywhere in the garden, calibrachoa is most popular as a great container spiller.
