cone-bearing Sir Herbert Beerbohm Tree arethe most common typeof what are get laid as gymnosperms : plants that produce come on the open of strobile . Collectively have it away as softwood tree , some have solid , hard wood while other conifer Grant Wood is soft and less fibrous . All coniferous tree carry cones and have needle or scalelike foliage . Often referred to as evergreens , not all conifers keep on their leaves year - round . There are hundreds of different cone-bearing trees , but most of them fall into several main groups .
Pines and Firs
Pine trees ( Pinus spp . ) include over 100 species . Hardy from U.S. Department of Agriculture plant hardiness zones 2 through 10 , pine tree comprise the most common eccentric of coniferous tree . Their farsighted , narrow needles are bound in bundles of two , three or five on branches that develop in ring known as lock . Each whorl represent a year ’s emergence . True true fir ( Abies spp . ) , hardy in USDA zones 3 through 7 , often have tiny resin pocket in their barque . Their erect cone cell place upright upright on topmost branch overcompensate in aromatic , 1 - inch leaves . The Douglas fir ( Pseudotsuga menziesii ) is not a dead on target true fir . Hardy in USDA zones 4 through 6 , it has typical , pitchfork - regulate bracts on its cones .
Cedars and False Cedars
Cedar trees can be divided into two chemical group : straight cedars and off-key cedars . True true cedar ( Cedrus spp . ) , brave in USDA zones 6 through 9 , have dense clusters of evergreen acerate leaf from stout , woody pin . The barrelful - regulate strobilus baby-sit on top of the branch . False cedarwood refers to several genera of conifers that share similar characteristic . characteristic include small , overlapping , graduated table - like parting ; pocket-size , upright strobilus that remain on the tree ; and redolent Mrs. Henry Wood . Examples of false cedar admit arborvitae ( Thuja spp . ) , intrepid in USDA zones 2 through 8 , white cedar ( Chamaecyparis thyoides ) , stalwart in USDA zones 4 through 8 , and Eastern scarlet cedar ( Juniperus virginiana ) , hardy in USDA zones 2 through 9 .
Spruce and Larches
Spruce trees ( Picea spp . ) , hardy in USDA zones 2 through 8 , have stiff , piercing , 1 - inch acerate leaf that develop from petite wooden pegs . They appear very similar to true fir trees , but the needles are stiffer , and spruce cone fall down rather than stand up . Their verticillated branches are similar to pine trees . larch tree ( Larix spp . ) , hardy in USDA zone 2 through 7 , are dissimilar from other conifer because they are deciduous . Their 1 - inch - long needles turn over yellow in the pin and then drop to leave the arm bare . Larix needle are soft , not discriminating like other conifer . Larches are also refer to as tamaracks .
Hemlock and Cypress
Hemlocks ( Tsuga spp . ) , hardy in USDA zone 3 through 7 , have short needles less than 1 - inch long that egress from pocket-size pin . They are sleep with for classifiable , soft , flag tops and branches . Cypress ( Cupressus spp . ) , unfearing in USDA zones 7 through 10 , have very tiny , scale - similar leaves that may be sharp and pointed . Cypress cones are round , woody and about 1/2 in in diameter .
Redwoods and Sequoias
Coast redwoods ( Sequoia sempervirens ) , hardy in USDA zone 7 through 9 , have piercing needles that look like miniature swords . The 1 - in redwood cones have thick , wrinkled scales . Dawn redwoods ( Metasequoia glyptostroboides ) , fearless in USDA zones 4 through 8 , and the gargantuan sequoia ( Sequoiadendron giganteum ) , hardy in USDA zone 6 through 8 , are often confused with coast redwood , but vary significantly . They have shorter needle and woody , egg - mold cones that are extremely arduous .
Junipers and Yews
Junipers ( Juniperus spp . ) , hardy in USDA zones 2 through 9 , and yews ( Taxus spp . ) , hardy in USDA zones 4 through 7 , might look like they produce berries , but they in reality support fleshy cone . Juniper leaf may be either scale - like , needle - like or both , and they have a very distinctive , strong olfactory perception . Their berrylike cones are silvery blue . Yew leaves are dark green on top and light green on bottom and distinctively pointed but not acuate . Yew cones are conduct on the female plant only ; they see like soft , bright red berries .
