Oxysepala, meaning sharp sepals, describes the especially long and pointed sepals (outer structure of the flower) of this columbine. They're a beautiful wine-red, the perfect complement to the yellow interior petals on these summertime flowers that bloom in lovely clusters. It comes from open areas of forest or rocky exposed meadows of Europe and Asia, currently designated as endangered in Switzerland. This very large, complex flower attracts hummingbirds, butterflies, and bees, as well as children that like "fairy flowers".
Mature size: 24 inches tall and clumping; happily self-sowing.
Minimum temperature: -5° F
