Tamarack or Larch?

By Christine Freeburn, Master Gardener

Many of you may have noticed the amazing yellow shades of the tamarack trees last October. They absolutely glowed in the landscape after the maple, oak and other deciduous trees had dropped their colourful leaves.tamarack-trees-208125_960_720

Tamarack and larches are from the Pinaceae family and the Larix genus with different species names to differentiate themselves. They are deciduous conifers, meaning they are evergreens that drop their needles in winter. Their bark seems flaky with reddish undertones. Leaves or needles are a light bluish green turning a bright yellow in autumn. They grow in whorls or tufts around the branch and give the tree a soft fluffy appearance. Cones are small.

European Larch is Larix decidua which grows here in the east. It tends to have droopy branches and grows in fields and open areas as it likes sun. Its needles tend to be a bit longer than the Tamarack needles and it’s cones are bigger.

Tamarack is Laris laricina which grows here in wet swampy areas in full sun. It is native to Canada.

Larch can live up to 850 years and grow 260′ tall while Tamarack are smaller, growing only 65′ high.larch-163340_960_720

There are several dwarf cultivars created for the home garden, however these trees do not do well in cities where they suffer from air pollution.

A strong softwood, Tamarack means ‘wood used for snowshoes’ in the Algonguin language.

Western Larch L.occidentalis grows in western Canada.

Watch for these bright pops of colour this fall.
