Aquilegia oxysepala
Oriental Columbine (Aquilegia oxysepala) is a hardy perennial wildflower from East Asia, grown for its purple and yellow spurred flowers that bloom in May. It is grown much like other columbines: give it good drainage and a cool, partly shaded spot.
Aquilegia oxysepala is a perennial flowering plant species in the genus Aquilegia (columbine) in the family Ranunculaceae. It is native to East Asia, with a range extending from southeastern Siberia to Japan. It produces purple and yellow flowers that bloom for three weeks in May. The plant has been used medicinally in China for thousands of years, while modern scientific research has determined that its extract has limited antioxidant qualities.
The American botanist Philip A. Munz reported in 1946 that A. oxysepala was broadly available in cultivation. He recorded that garden specimens of A. oxysepala were sometimes labelled as other species, while Aquilegia buergeriana was sometimes erroneously labelled A. oxysepala var. yabeana.
Aquilegia oxysepala is native to East Asia, with a range extending from southeastern Siberia to Japan. The species prefers temperate biomes. It is found on the edges of forests and on grassy slopes at elevations between 400 m (1,300 ft) and 2,700 m (8,900 ft) above sea level.
In China, A. oxysepala has been used as a dietary supplement and medicine for thousands of years. There, A. oxysepala has been used to treat diseases in women such as irregular menstruation and intermenstrual bleeding. While the antioxidant properties of its extract are known, with its medicinal use possibly attributable to the extract's good scavenging of superoxide anion radicals, it is inferior to the common dietary supplement ascorbic acid. Research has also determined A. oxysepala possesses antibacterial qualities.
