Dahurian larch is a deciduous conifer that forms vast taiga forests in Siberia, valued for extreme cold tolerance, and is rarely grown outside its native range. The key to growing it is cold hardiness and full sun; it is not a common garden plant in warm climates.

About
Larix gmelinii, the Dahurian larch or East Siberian larch, is a species of larch native to eastern Siberia and adjacent northeastern Mongolia, northeastern China (Heilongjiang), and the Korean Peninsula.
Where it grows
Larix gmelinii forms enormous forests in the eastern Siberian taiga, growing at 50–1,200 m altitude on both boggy and well-drained soils, including on the shallow soils above permafrost. It is unique in two respects, being the northernmost tree in the world, reaching 73° 04' 32" N 102° E as creeping forms of the trees in the tundra of the Taymyr Peninsula, 72° 55' 07" N 106° 08' E, and as comparatively vertical growing single trees and small groups of trees, 72° 31' N 105° 03' E at the Lukunsky grove and 72° 28' N 102° 15' E at Ary-Mas as the subtundra sparse forests which are situated both in the Taymyr Peninsula, Khatanga river basin, and also the most cold-hardy tree in the world, tolerating temperatures below -70 °C in the Oymyakon–Verkhoyansk region of Yakutia. One tree in Yakutia was recorded as being 919 years old.
