Fruit - Follicles to 3cm long, beaked.

Flowering - April - July.

Habitat - Rocky ledges, rocky slopes, low woods. Also cultivated.

Other info. - The spurs of the petals contain nectaries and are very attractive to insects equipped with long proboscises. This and other species of Aquilegia are highly cultivated and easy to grow.
In Italian "Aquila" means "Eagle" and indeed the genus is so named because of the talon shaped spurs of the petals.
Steyermark lists two forms for the plant in Missouri. Form canadensis, (pictured above), has the typical red and yellow corolla. Form flaviflora (Tenny) Britt. has a corolla which is completely yellow. This form is rare. Some cultivated forms have white or pink corollas and can be double flowered also.
