About Aquilegia viridiflora Pall.
Aquilegia viridiflora Pall. is a herbaceous perennial plant. It reaches 15 to 50 cm (5.9 to 19.7 in) in height, with stems that are hairy or glandular, and often branch near the top. It has a small number of basal leaves: these are biternate, mostly smooth, and borne on stalks up to 18 cm (7.1 in) long. This species produces 3 to 7 nodding flowers that measure 1.5–2 cm (0.6–0.8 in) across. Flowers are either yellowish-green (in the variety viridiflora) or dark purple (in the variety atropurpurea). The sepals and petals reach 1.5 cm (0.6 in) or less in length. Petals have straight or slightly incurved nectar spurs that measure 1.2 to 1.8 cm (0.5 to 0.7 in) long. Aquilegia viridiflora is native to Japan, Mongolia, Russia (southern Siberia regions Buryatia, Tuva, and Zabaykalsky Krai, plus Amur Oblast in the Russian Far East), and multiple northern Chinese provinces: Gansu, Hebei, Heilongjiang, Hubei, Jilin, Liaoning, Nei Mongol, Ningxia, eastern Qinghai, Shaanxi, Shandong, and Shanxi. It grows in forests, grassy slopes, damp areas, and beside streams, at altitudes from 200 to 2,400 m (660 to 7,870 ft). It flowers from May to July, and is pollinated by early spring bees belonging to the genus Anthophora. It is cultivated as an ornamental plant.
