About 35 species make up the genus Picea – the spruces. Like other members of the family Pinaceae, they are evergreen conifers, related to the hemlocks (Tsuga spp.), firs (Abies spp.) and Douglas firs (Pseudotsuga spp.); however, their closest relatives are the pines (Pinus spp.).
Clad in evergreen needles and decorated with handsome woody cones, pine trees (Pinus spp.) are among the most recognizable trees in the world. In addition to their aesthetic charm, pine trees provide a variety of resources to the ecosystems in which they grow.
The term “cedar” is applied to so many different types of trees that many tree professionals, farmers and botanists refer to trees of the genus Cedrus as “true cedars.”
Larches are medium to large trees of the genus Larix. Scientists debate the finer points of the group’s interrelationships and classification, but most recognize about 10 to 15 species.
Examination of the needles helps to distinguish fir trees from lookalikes. Fir needles are generally soft to the touch, flat in cross section and attach to the branch via suction-cup-like structures
Arborvitaes are evergreen conifers, native to North America and Asia. Thanks to their hardy nature, they are quite popular among homeowners, arborists and landscape designers.
Coastal redwoods (Sequoia sempervirens) are among the most famous trees in the world. Most of this fame precipitates from their incredible size, as they are among the tallest species on Earth.
Giant sequoias (Sequoiadendron giganteum) are famous for being some of the largest organisms on the planet. Known colloquially as big trees, Sierra redwoods, Sequoiadendrons, or simply sequoias, these trees have been one of the most important species in Northern California for millions of years.
Taiwania trees (Taiwania cryptomerioides) are large evergreens, native to East Asia. Relatively poorly known among North American tree enthusiasts, these immense trees can make interesting specimen trees in yards and commercial areas, provided that you can find specimens for sale.
Found in swamps, floodplains and riparian areas throughout the Deep South, bald cypresses (Taxodium distichum) are some of the most iconic trees in the country.
