It is a small to medium-size deciduousDeciduous means "temporary" or "tending to fall off". Deciduous plants are those that lose their foliage for part of the year. In most cases, the foliage loss coincides with the incidence of winter in temperate or polar climates, but some plants lose thei coniferous treeThis article is about the biological organisms known as trees. For other meanings of the word see tree (disambiguation). oak tree in Denmark A tree can be defined as a large perennial woody plant. Though there is no set definition of size, it is generally reaching 10-20 m tall, with light blue-green needle-like leavesThis article is about the leaf a plant organ. See Leaf (disambiguation) for other meanings. In botany, a leaf is an above-ground plant organ specialized for photosynthesis. For this purpose, a leaf is typically flat and thin, to expose the chloroplast con 2-3 cm long which turn bright yellow before they fall in the autumn, leaving the pale pinkish-brown shoots bare until the next spring.

The central Alaskan population, separated from the eastern Yukon populations by a gap of about 700 km, is treated as a distinct variety Larix laricina var. alaskensis by some botanists, though others argue that it is not sufficiently distinct to be distinguished.
