There are 35 known species of spruce (Picea spp.), which is a coniferous evergreen tree in the pine family. Spruce is found in the northern temperate and boreal regions. These trees range from 65 to 200 feet (20 to 60m) tall. The sharp, square needles help to distinguish spruce from pine and fir, and the dangling cones of spruce differentiate from fir. While fir twigs have needles growing from two sides of the twig, creating a flat shape - spruce needles are attached singly to the branches in a spiral pattern. The early summer growth of spruce twig tips can be steeped in hot water for a vitamin C rich tea. Fresh or dried spruce tips are also used to flavor spruce beer, and the inner bark can be dried and ground into flour like fir.
