It 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 72° 30' N at Ary-Mas (102° 27' E) in the Khatanga River valley on the Taymyr Peninsula, and also the most cold-hardy tree in the world, tolerating temperatures below -70 °C in the Oymyakon–Verkhoyansk region of Yakutia.

It is a medium-sized deciduous coniferous tree reaching 10-30 m tall, rarely 40 m, with a trunk up to 1 m diameter. The crown is broad conic; both the main branches and the side branches are level, the side branches only rarely drooping. The shoots are dimorphic, with growth divided into long shoots (typically 5-30 cm long) and bearing several buds, and short shoots only 1-2 mm long with only a single bud. The leaves are needle-like, light green, 2-3 cm long; they turn bright yellow to orange before they fall in the autumn, leaving the variably downy reddish-brown shoots bare until the next spring. Deciduous means temporary or tending to fall off (deriving from the Latin word decidere, to fall off). ...

The cones are erect, ovoid, 1-2 cm (rarely 2.5 cm) long, with 15-25 moderately reflexed seed scales; they are green (rarely purple) when immature, turning brown and opening to release the seeds when mature, 3-5 months after pollination. The old cones commonly remain on the tree for many years, turning dull grey-black.

The closely related Prince Rupprecht's Larch (Larix principis-rupprechtii) is treated as a fourth variety (L. gmelinii var. principis-rupprechtii) by many botanists; it occurs in a disjunct region in the Wutai Shan mountains west of Beijing, separated from typical L. gmelinii by about 1000 km, and differs in larger (2-4 cm) cones with more scales.

Dahurian Larch intergrades with the closely related Siberian Larch L. sibirica of central and western Siberia where their ranges meet along the Yenisei Valley; the resulting hybrid is named Larix × czekanowskii. The Siberian Larch, or Russian larch, (Larix sibirica) is a frost-hardy tree which occurs naturally in northeastern Russia and western Siberia. ... // In biology, hybrid has two meanings. ...

The scientific name honours Johann Georg Gmelin. Due to the species' variability, it has acquired numerous synonyms in the botanical literature, including L. cajanderi, L. dahurica, L. kamtschatica, L. komarovii, L. kurilensis, L. lubarskii, L. ochotensis. Johann Georg Gmelin (August 8, 1709 - May 20, 1755) was a German naturalist, botanist and geographer. ... In scientific classification, synonymy is the existence of multiple systematic names to label the same organism. ...

Dahurian Larch is occasionally grown in botanical gardens in Europe and North America; it is not an easy tree to grow in areas with mild winters as it is adapted to a long period of winter rest; the warm winter weather in Britain can tempt it into leaf as early as the start of January, with the tender young leaves then being killed by the next frost. In its native region, temperatures above freezing do not occur until late May or June, with no further frost until the brief summer is over.
