Aquilegia (common names: granny's bonnet, columbine) is a genus of about 60–70 species[2] of perennial plants that are found in meadows, woodlands, and at higher altitudes throughout the Northern Hemisphere, known for the spurred petals of their flowers.
The genus name Aquilegia comes from the Latin “Aquila”, or “eagle”; this is in obvious reference to the spurred, “hook” shapes within the blooms, that many gardeners say resemble an eagle's talons.
Perennial herbs, with woody, erect stock, roots forming thick rhizomes. The basal leaves are compound, 1–3 ternate, blades 3-lobed -partite, and lobes lobulate and obtuse. The cauline leaves are similar to the basal ones, while the upper ones are bract like.
The hermaphrodite (bisexual) flowers are terminal to stem and branches. They are usually pentamerous (with five spreading perianth petaloid sepal segments). Five tubular honey-leaves are semi erect with a flat limb and spurred or saccate at the base. The spur is directed backwards and secretes nectar. Stamens are numerous (often more than 50) in whorls of 5, the innermost being scarious staminodes. There are ten membranaceous intrastaminal scales. There are five pistils and the Carpels are free.
The fruit has several (five to 15) follicles which are semi erect and slightly connate downwards. These hold many seeds and are formed at the end of the pistils. The nectar is mainly consumed by long-beaked birds such as hummingbirds. Almost all Aquilegia species have a ring of staminodia around the base of the stigma, which may help protect against insects. Chromosome number is x=7.
