The famous Clementine Columbines are hybrids with fully doubled flowers. The blue, red, purple and hot pink (Salmon Rose) are big favorites.
The Wild Columbines Many people think columbines are the loveliest flowers of all, and they are certainly important in the wildflower world. Many important species are North American natives. Everyone in the Northeast loves the Wild Eastern Columbine, the beautiful smallish red one, Aquilegia canadensis, and of course, everyone in the Rockies loves the State Flower of Colorado, the large, blue Colorado Columbine, A. caerulea. There are important species native to Europe and Japan as well.
