Larix laricina (Tamarack, American Larch) Pinaceae

Larix Laricina, commonly known as tamarack or American larch, is a deciduous conifer,  one of only few species of conifers that are not evergreen and the only native deciduous conifer of Illinois. In the fall the needles of this small to medium sized tree turn a beautiful golden yellow and fall off.

The fruit is a small upright cone which stays on the branch for a year or two. The seeds which are about .12” with a .25” wing are primarily wind dispersed. 

Trunk | Bark: The bark is thin and smooth on young trees becoming thicker and scaly as the tree grows. The tree has a pyramidal crown and can reach a height up to 50’ to 75’.

Life span: Trees live up to about 180 years.
