The tamarack would not make a very good pine tree for Christmas since the tamarack turns yellow in autumn and drop their needles so they would be rather bare looking even at the start of the Christmas season.
When I think of trees with needles, I don’t picture them bare during the winter but Tamarack trees do turn a pretty yellow in the fall before they shed their needles. In the spring, new growth emerges with 10 to 20 needles per cluster and make the tree green again.
