columbine
Any of approximately 80 species of perennial herbaceous plants constituting the genus Aquilegia, in the buttercup family, native to Europe and North America. They are distinctive for their five-petaled flowers with long, backward-extending spurs. Sepals and petals are brightly coloured. A. caerulea and A. chysantha are native to the Rocky Mountains. The wild columbine of North America (A. canadensis), bearing red flowers with touches of yellow, grows in woods and on rocky ledges from southern Canada southward. Many garden hybrids are cultivated for their showy flowers.

columbine
columbine (kŏl'əmbīn), any plant of the genus Aquilegia, temperate-zone perennials of the family Ranunculaceae (buttercup family), popular both as wildflowers and as garden flowers. Columbines have delicate and attractive foliage and flower petals with long spurs that secrete nectar. The common Eastern red-and-yellow-flowered wild columbine (A. canadensis), frequenting rocky places, is also called rockbell; it is a favorite of hummingbirds, and Native Americans made an infusion of the seeds for headache and fever. The blue-and-white-flowered A. coerulea of the Rockies is the state flower of Colorado. The common European columbine (A. vulgaris), blue, white, or purple flowered, has been the source of many cultivars-some double and of various soft colors. Columbine is classified in the division Magnoliophyta, class Magnoliopsida, order Ranunculales, family Ranunculaceae.

Aquilegia (Columbine; from Latin columba "dove") is a genus of about 60-70 species[1] of perennial plants that are found in meadows, woodlands, and at higher altitudes throughout the Northern Hemisphere, known for the spurred petals [2] of their flowers.

Etymology
The genus name Aquilegia is derived from the Latin word for eagle (aquila), because the shape of the flower petals, which are said to resemble an eagle's claw.
"Columbine" is derived from the Latin word for pigeon (columba). Another old-fashioned name for this cottage garden plant is "Granny's Bonnet" as the shape of the bloom resembles the mob caps old women used to wear.
Description
Relatives
Columbines are closely related to plants in the genera Actaea (baneberries) and Aconitum (wolfsbanes/monkshoods), which like Aquilegia produce cardiogenic toxins.[4]
Insects
They are used as food plants by some Lepidoptera (butterflies and moths) caterpillars. These are mainly of noctuid moths – noted for feeding on many poisonous plants without harm – like Cabbage Moth (Mamestra brassicae), Dot Moth (Melanchra persicariae) and Mouse Moth (Amphipyra tragopoginis). The Engrailed (Ectropis crepuscularia), a geometer moth, also uses columbine as larval foodplant.
Cultivation
Several species are grown in gardens, including the European Columbine (A. vulgaris), a traditional garden flower in many parts of the world.[5] Numerous cultivars and hybrids have also been developed as well. They are easy to propagate from seed.
Columbine is a perennial, which propagates by seed. It will grow to a height of 15 to 20 inches. It will grow in full sun, however, prefers growing in partial shade and well drained soil, and is able to tolerate average soils and dry soil conditions. Columbine is rated hardiness of Zone 3 so does not require mulching or protection in the winter.[6][7]
Large numbers of hybrids are now available for the garden, since the British A vulgaris was joined by other European and N American varieties. [8] Aquilegia species are very interfertile, and will self sow.[9]
Uses
The flowers of various species of Colombine were consumed in moderation by Native Americans as a condiment with other fresh greens, and are reported to be very sweet, and safe if consumed in small quantities. The plant's seeds and roots are highly poisonous however, and contain cardiogenic toxins which cause both severe gastroenteritis and heart palpitations if consumed as food. Native Americans used very small amounts of Aquilegia root as an effective treatment for ulcers. However, the medical use of this plant is better avoided due to its high toxicity; columbine poisonings may be fatal.[4]
Culture
The Colorado Blue Columbine (A. caerulea) is the official state flower of Colorado (see also Columbine, Colorado).
Evolution
Columbines have been important in the study of evolution. It was found that Sierra Columbine (A. pubescens) and Crimson Columbine (A. formosa) each have specifically adapted pollinators, with hawkmoths that can pollinate one species while usually failing to pollinate the other. Such a "pollination syndrome", being due to flower genetics, ensures reproductive isolation and can be a cause of underlying speciation.[10]
Petal Spur Evolution
Aquilegia petals show an enormous range of petal spur length diversity ranging from a centimeter to the 15 cm spurs of Aquilegia longissima. Interestingly, it was shown that this amazing spur length diversity is achieved solely through changing cell shape, not cell number or cell size. This suggests that a simple microscopic change can result in a dramatic evolutionarily relevant morphological change.[2]
