Document Summary

The top portion of the conifer is shiny and the bottom is silvery. Balsam fir is a small to mid-sized evergreen conifer. They are upright trees, which mean they stand still. 23m in height and can live up to a maximum age of 200 years. It is also a provincial tree of new. According to history, balsam fir has survived the ice age, which is fairly significant. The needles are flat with dark green colour and it is about 2-3cm long (1in). There is a thin, closely overlapping fan-shaped scale near the center of the cone. The cone matures and ripens during the first fall in late august and early september. Both the male and female cones are on the same tree. The male cones are about 4 mm long while female cones are around 4-10cm long. In this case, female cones can be easily identified.
