Rocky Mountain columbine
This beloved Rocky Mountain native perennial is prized for beautiful blue and white, long spurred flowers. Late spring brings tall flower stems rising above the clumps of ferny foliage to around 2 ft. tall. The large, upward facing, two toned blossoms are highly attractive to hummingbirds and hawk moths. Grow Colorado's state flower with light shade and well-draining soils and medium moisture. Can seed about when happy. Often mentioned as deer resistant.
