About

Aquilegia canadensis, the Canadian columbine, Canada columbine, eastern red columbine, or wild columbine, is a species of flowering plant in the buttercup family. It is a perennial plant that is native to the woodlands and rocky areas in eastern North America in both the United States and southern Canada. It readily hybridizes with other plants in the columbine genus and is a common garden plant.

How to grow it

Aquilegia canadensis is a highly decorative plant, valued for its attractive foliage and showy flowers. For this reason it is widely grown outside its native region, in temperate regions of the Northern Hemisphere.

The plant grows best in light to moderate shade, and prefers well-drained sandy loams, thriving in limestone-based or circumneutral soils. Plants grown in soils that are too moist or rich may produce weak plants, and have a shorter lifespan. Despite being a short-lived perennial, it self seeds very readily, allowing it to persist for many years. Seedlings generally flower in their second year. Cool-moist stratification at 5 °C (41 °F) for three to four weeks may speed sprouting, but it is not required for germination. Mature plants are able to tolerate periods of drought, but growth is best under consistent moisture. Seeds can be stored for three to four months in seedbags at 5 to 6 °C (41–43 °F).

Where it grows

Aquilegia canadensis is a native to eastern and central North America, from New Brunswick to northern Florida and west to Saskatchewan and Texas. It is the sole native columbine from eastern North America, though smallflower columbine (Aquilegia brevistyla) is reported as far east as Clay County, Minnesota and northern parts of Ontario and the non-native European columbine (Aquilegia vulgaris) has escaped from cultivation in Canada, the northeast, and parts of the south.
