Plant Taxonomy of Columbine Flowers:
Plant taxonomy classifies columbine plants, in general, as Aquilegia. For instance, Aquilegia canadensis is the red columbine.
Plant Type for Columbine Plants:
Columbine plants are herbaceous flowering perennials.
Characteristics of Columbine Plants:
Columbine plants come in many colors; some are even bi-colored. Columbines can have red, yellow, white, blue, pink or purple blossoms. Columbine flowers are airy plants with attractive foliage (clover-like when young), reaching ca. 2 feet in height (taller when in full bloom). Columbine plants bloom in late spring to early summer and self-seed readily if you don't deadhead (see below under Care).
Planting Zones for Columbine Flowers:
Grow columbine plants in planting zones 3-9. There are columbine flowers native to many lands. Aquilegia canadensis, for instance, indigenous to the woods of eastern North America, is a wildflower often remarked upon by hikers for its bluish-green foliage.
Sun and Soil Requirements for Columbine Plants:
There are plenty of exceptions, but "partial shade" is the standard recommendation for columbine plants. Grow columbine flowers in a well-drained soil. Often dwelling on rocky ledges in the wild, the drought resistance displayed by such columbine flowers as Aquilegia canadensis make them good candidates for xeriscaping.
