Columbine Aquilegia (common names: Grannys Bonnet or Columbine) 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. Columbine is a hardy perennial, which propagates by seed. It will grow to a height of 15 to 20 inches. It will grow in full sun; however, it prefers growing in partial shade and well drained soil, and is able to tolerate average soils and dry soil conditions. Columbine is rated at hardiness zone 3 in the USA so does not require mulching or protection in the winter. The flowers of various species of columbine 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 plants 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 a treatment for ulcers.[citation needed] However, the medical use of this plant is better avoided due to its high toxicity; columbine poisonings may be fatal.[5] An acute toxicity test in mice has demonstrated that ethanol extract mixed with isocytisoside, the main flavonoid compound from the leaves and stems of Aquilegia vulgaris, can be classified as non-toxic, since a dose of 3000 mg/kg did not cause mortality. en.wikipedia.org/wiki/Aquilegia
