|---|---|---|---|---|---|
| Ranunculaceae | Aquilegia canadensis | Canada Columbine, Eastern Columbine | Forests, woodlands, rock outcrops, especially (though by no means entirely) on calcareous or mafic substrates. | NS, QC, ON, MB, and SK south to Panhandle FL, s. AL, ne. MS (Tishomingo County), w. TN, c. AR, and se. OK; disjunct in Edwards Plateau of TX. |  |
| Ranunculaceae | Aquilegia vulgaris | European Columbine, Garden Columbine | Disturbed areas, recently appearing in natural areas (such as grassy balds, in thin soils around rock outcrops). | Native of Europe. Many varieties have been named; there seems little utility in trying to apply these names to the cultivated plants (often cultivars) rarely persistent or weakly naturalized in our area. |  |
