Botanical Name:Larix laricina
Common Name:tamarack, American larch
Family Name:Pinaceae – pine family
General Description:Larix laricinais native to the northern tier of North America and is considered one of the most cold hardy of trees. It is native in acidic bogs and swamps but can grow in more upland sites provided there is adequate moisture. According to The Morton Arboretum, tamarack, which is native in the Chicago area, is on the threatened species list for Illinois. For this reason they suggest it should never be collected from the wild and plants should only be purchased from reputable nurseries. Larix laricina is intolerant of shade, drought, heat or pollution. As a deciduous conifer it shares many of the same morphological characteristics as its European relative, Larix decidua; however, it is less adapted to landscape conditions and is infrequently used. There are a few unique cultivars available from specialty growers.
