Most species of spruce grow to the height of 60 to 200 feet. Sitka spruce is the tallest species of spruce that can reach 300 feet in height.
Spruce tree is conical in shape thanks to whorled branches. Tree grows very fast, from 6 to 11 inches per season, even though some species can grow 60 inches per year.
Spruce has needle-like leaves that are spirally arranged on the branches. They grow from the peg-like structure called pulvinus. Leaves are shed after 4 to 10 years.
Each spruce tree produces male and female cones. Young cones are green. Mature cones are brown in color. Cones with ovules (female cones) are larger than cones with pollen (male cones).
Wind carries pollen from the male cones to the female cones. Female cones open three years after pollination to release mature seed.
