About

Aquilegia formosa, the crimson columbine, western columbine, sitka columbine, or (ambiguously) "red columbine", is a common wildflower native to western North America, from Alaska to Baja California, and eastward to Montana and Wyoming.

Where it grows

Within its range, the crimson columbine can be found in most kinds of habitat (chaparral, oak woodland, mixed-evergreen or coniferous forest). It is not found on desert floors, nor at altitudes above 3,300 metres (10,830 ft), and it is absent from the Central Valley of California. It prefers moist locations such as stream banks.
