European Columbines have been cultivated in British gardens since at least the 14th century. Parkinson and Gerard illustrated many double forms in their herbals of the 16th and 17th centuries. Single and double columbines were grown in America before 1700, and it is likely that Jefferson had both types. ‘Adelaide Addison’ is a modern name applied to a colorful double columbine similar to forms long in cultivation. Bees, butterflies, and hummingbirds are all attracted to the flowers. zone3,zone4,zone5,zone6,zone7,zone8,zone9
