Small plant with beautiful, intricate flowers, blue, purple, white or pink, with four long backward spurs, nodding at the end of the flowerstalks.  Leaves with three leaflets; each leaflet delicately and intricately lobed. 

Common garden plant that sometimes escapes into the wild and sometimes turns up in Wildwood. Has been seen in the floodplain of Connelly's Run and on the low cliffs under the powerline along Wildwood Drive. 

Unmistakable.  The native Canada columbine (Aquilegia canadensis) has similar flowers, but they are bicolored red and yellow and longer than wide with protruding yellow stamens.  The leaves are similar.
