Larix laricina / American larch / tamarack
Larix laricina, as described in 1873 by Karl Heinrich Emil Koch (1809 – 1879), in Dendrologie, 2nd edition, is commonly known as tamarack, hackmatack, eastern larch, black larch, red larch, or, more widely in the nursery trade as American larch. The word tamarack is the Algonquian name for the species and means "wood used for snowshoes." The species name means "larch-like" in the Latin language, referring to its resemblance to European larch which Linnæus, at the time, called Pinus larix.
Early settlers would leave a high stump after felling the tree. The stump would be harvested being careful to leave as much of the curving root system before extracting the stump from the ground. These naturally curved pieces of wood were then used to make ships knees in boat building to save the laborious process of steaming and then bending wood for the boat's ribs. Traditional boat builders in northern New England still harvest tamarack for this purpose.

Description. American larch is a small to medium-size boreal coniferous and deciduous tree reaching 30 to 60 feet (10 – 20 m) tall, with a trunk up to 24 inches (60 cm) diameter, measured at breast height.
- Bark is tight and flaky, pink, but under flaking bark it can appear reddish.
- Shoots are orange-brown in color and glabrous in texture. Buds are dark red, subtended by a ring of hairlike bracts and glabrous.
- Leaves are needle-like, 0.8 to 1.2 inches (2 – 3 cm) long, light Blue-green in color, turning bright yellow before they fall in the autumn, leaving the pale pinkish-brown shoots bare until the next spring. The needles are produced spirally on long shoots and in dense clusters on long woody spur shoots.
- Seed cones are the smallest of any larch, only 0.4 to 0.9 inch (1 – 2.3 cm) long, with 12 to 25 seed scales; they are bright red in color at first, later turning brown and opening to release the seeds when mature, 4 to 6 months after pollination.
- Seed bodies are 0.08 to 0.12 inch (2 - 3 mm) long with 0.16 to 0.24 inch wings.

Distribution. This species is native to Canada, from eastern Yukon and Inuvik, Northwest Territories east to Newfoundland, and also south into the northeastern United States as far down as to Cranesville Swamp, Maryland, and as far west as Minnesota. There is also a disjunct population in central Alaska. It is very cold tolerant, able to survive temperatures down to at least −85°F (−65°C), and commonly occurs at the arctic tree line at the edge of the tundra. Trees in these severe climatic conditions are smaller than farther south, often only 16 feet (5 m) tall. Tamarack can tolerate a wide range of soil conditions but grows most commonly in swamps in wet to moist organic soils such as sphagnum peat and woody peat. The tree is found on mineral soils that range from heavy clay to coarse sand; thus texture does not seem to be limiting. Although tamarack can grow well on calcareous soils, it is not abundant on the limestone areas of eastern Ontario.
Tamarack is commonly an early invader, and is generally the first forest tree to invade filled-lake bogs. In the lake states, tamarack may appear first in the sedge mat, sphagnum moss, or not until the bog shrub stage. Farther north, it is the pioneer tree in the bog shrub stage. Tamarack is fairly well adapted to reproduce successfully on burns, so it is one of the common pioneers on sites in the boreal forest immediately after a fire.

I am looking for some plants to put on 1.5 acre lawn that will help wildlife forage in winter here in Southern Michigan. Soil is moist in some places and clay in others. Thanks for your help.
this species will work well for the conditions you describe.
I have a European larch tree which I believe needs a bit of help. It must be about 50-years old, and stands next to a white pine. I have been through a few blogs and no one agrees on which mix would be best for the tree. It's in a dense clayey ground where crushed and very dense bedrock starts at 24 inches. It is in the grassy area, so not much natural recycling of organic matter for it. It is 40 to 45 feet tall, extends (branches) 30-32 feet in diameter and the base of the trunk is 25 inches in diameter.
Thank you.
for a plant so old and so large, there's nothing you can do about its "mix" of planting medium. It would help to know where you're trying to grow it. Larch have evolved to thrive in cool climates with cold winters. They also like fairly damp soil conditions.
question regarding Roots. I have a septic field and want to know how far out the roots can reach?
typically drip line +10% ...
Is the Tamarack black walnut tolerant?
