Coniferous forests grow in North America, Europe, and Asia near mountains. Since they live in colder areas they are evergreen trees. They grow needles instead of leaves and cones instead of flowers. Common conifers would be pine, Spruce, Columbines, larch, fireweed, giant sequoia, aspen, and firs. Precipitation falls from three hundred to nine hundred millimeters annually, this depends on the forests location, in the northern boreal the winters are long, cold, and dry in the summer its usually hot and moist. In the lower latitudes the rain is distributed evenly.
