northernmost tree in the world, reaching 73° 04' 32" N 102° 00' 00" E as creeping forms of the trees in the tundra of the Taymyr Peninsula, 72° 55' 07" N 106° 08' E as comparatively vertical growing single trees, 72° 31' N 105° 03' E at 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. 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, daily minimum temperatures above freezing do not occur until late May or June, with no further frost until the brief summer is over. Larix gmelinii cone scales are used as food by the caterpillars of the tortrix moth Cydia illutana.
