Family Scientific Name: Pinaceae
Family Common Name: Pine family
Scientific Name: Larix laricina (Du Roi) K. Koch.
Common Name: Tamarack

General Distribution: L. laricina is found in boreal forests on wet, poorly drained sphagnum bogs and muskegs. It is also on upland mineral soils. It ranges from Alaska and Yukon across Canada to New Brunswick ,Newfoundland,St. Pierre and Miquelon south throuth the eastern United States to West Virginia. It is also found in the midwestern states from Michigan, Minnesota, Wisconsin, and Ohio.
Propagation Goal: Plants
Propagation Method: Seed
Product Type: Container (plug)
Propagule Processing: Seeds exhibit physiological dormancy.
Pre-Planting Treatments: Seeds are placed in cold moist stratification for 0 to 42 days. Germination occurs at 30D/20N C alternating temperature cycle.
Germination is greater in light than in dark.
