Paraquilegia microphylla is a small cushion-forming perennial from cliffs and rock fissures in the high mountains of Siberia, Central Asia, the Himalayas and Japan. It is rare in cultivation and is best grown by experienced rock gardeners in a cool, sharply drained, lime-rich setting.

About
Paraquilegia microphylla is a species of perennial flowering plant in the family Ranunculaceae. It is native across a range spanning Siberia, Central Asia into the Himalayas, and east to Japan. The species has flowers that vary in color across its range, with P. microphylla in the western Himalayas possessing small white flowers while those in the eastern Himalayas produce larger lilac flowers.
P. microphylla is the most common member of the genus Paraquilegia in cultivation, though it is often misidentified as Paraquilegia anemonoides. P. microphylla seeds have been introduced to gardeners outside its native range from seed-collecting expeditions to western China and the Himalayas, though the species remains rare in cultivation.
How to grow it
Paraquilegia plants are cultivated by rock gardeners, with Nold observing that the genus is generally appraised as the domain of only "the most experienced growers". P. microphylla is the most common species of Paraquilegia in cultivation, though it is still comparatively rare. When exhibited, it is often misidentified as P. anemonoides. Several seed-collecting expeditions to western China and the Himalayas, a practice common during the 20th century, brought seeds back to both the United Kingdom and the United States.
Where it grows
Paraquilegia microphylla is native across a range spanning Siberian Russia, Central Asia into the Himalayas, and east to Japan. The plant is present across the Himalayas, only absent in the most westerly portions of this mountain range. The Chinese range of this species encompasses mountainous western China, including Tibet and Xizang, as well as Sichuan and Xinjiang. The Flora of China recorded the plant's range including Kazakhstan, Nepal, northern Pakistan, Sikkim in Bhutan, and Tajikistan.
