Aquilegia vulgaris
Aquilegia desertorum
Aquilegia vulgaris is cultivated as an ornamental and occasionally escapes into disturbed habitats. Most plants have blue or purple flowers (the wild type), but horticultural races with white or reddish flowers sometimes become established. Many cultivated columbines are derived from hybrids between A. vulgaris and related species. Some of our escaped plants are probably descended from such hybrids.

Aquilegia desertorum is very similar to A. canadensis. Further research is needed to determine whether they are really distinct at the species level. The leaflets may be weakly viscid abaxially in plants from the Zion National Park area, Utah.
Plants from the eastern and southern parts of the range of Aquilegia desertorum have usually been considered a distinct species, A. triternata, mainly because of their longer sepals and petal blades (sepals narrowly ovate to lanceolate, 12-20 × 4-8 mm, apex acuminate, petal blades 6-12 mm in A. triternata versus sepals ovate or elliptic-ovate, 7-13 × 3-6 mm, apex obtuse or acute, petal blades 3-5 mm in A. desertorum in the strict sense). These sepal and petal types intergrade over much of central Arizona, however, and other characteristics supposedly diagnostic for A. triternata (leaves not glaucous, 3×-ternately compound) are scarcely correlated with the flower characteristics or with one another.
The Navaho-Kayenta used Aquilegia desertorum as an aid in ceremonies (D. E. Moerman 1986).
