The leaves are needle like, but are flat, soft, slender, 3/4 to1-1/4 inches long and borne in clusters on spur like branches. In the spring the needles are bright green and very soft and flexible. In the fall they turn a dull yellow just before falling off.

The cone is small and nearly spherical, 1/2 to 3/4 inches long.  The young cones are reddish to green in color, turning brown as they mature often remaining on the tree for several years.  As they mature and open in the fall, they liberate small, winged seeds.

European Larch Twigs

The twigs are light brown to gray in color, and covered with numerous tiny spurs or short branches.  The rough bark separates on the surface into thin, reddish brown scales.
