Spruce (Picea) –
Spruce (Picea spp.) have rigid, sharp, 1-inch needles that grow out of tiny wooden pegs. They appear very similar to fir trees, but the needles are stiffer, and spruce cones hang down rather than standing up on top of the branch. Their whorled branches resemble pine trees. These trees can get 60-180ft tall and are usually conical. There are some weeping and dwarf varieties.
