Fraser recorded the development of a single white spruce tree from 1926 to 1961. Apical growth of the stem was slow from 1926 through 1936 when the tree was competing with herbs and shrubs and probably shaded by larger trees. Lateral branches began to show reduced growth and some were no longer in evidence on the 36-year-old tree.

Sitka spruce is a long-lived tree, with the oldest known individual just under 600 years old. [7] Because it grows rapidly under favorable conditions, large size may not indicate exceptional age. The Queets Spruce has been estimated to be only 350 to 450 years old, but adds more than a cubic meter of wood each year.
Foliage and cones. Red spruce is a perennial, [8] shade-tolerant, late successional [9] coniferous tree that under optimal conditions grows to 18–40 m (59–131 ft) tall with a trunk diameter of about 60 cm (24 in), though exceptional specimens can reach 46 m (151 ft) tall and 100 cm (39 inches) in diameter.
