Trees are the largest and longest-lived organisms on Earth. A single coast redwood can stand over 350 feet tall and live for more than 2,000 years. But trees aren't just impressive in size - they're fundamental to how ecosystems function. They filter air, anchor soil, regulate water cycles, and provide habitat for thousands of other species. The planet has roughly 3 trillion trees across 73,000 known species, and every continent except Antarctica has native tree cover.
This page lists 50 well-known tree species in alphabetical order. Each entry includes the botanical family, native region, maximum height, and leaf type. Whether you're identifying trees on a hike, choosing what to plant in your yard, or researching species for a school project, an alphabetical reference makes it easy to look up what you need.

Deciduous vs. Evergreen Trees
The most fundamental distinction among trees is how they handle their leaves. Deciduous trees drop their foliage every autumn, entering a dormant state through winter before leafing out again in spring. Maples, oaks, elms, and birches are all deciduous. This strategy conserves water and energy during cold months when photosynthesis would be inefficient anyway. The fall color displays that draw millions of visitors to New England and the Appalachians each year happen because deciduous trees break down chlorophyll before dropping their leaves, revealing the yellow, orange, and red pigments that were hidden underneath all summer.
Evergreen trees keep their leaves (or needles) year-round. Pines, spruces, firs, cedars, and hemlocks are the conifers most people think of, but plenty of broadleaf trees are evergreen too - holly, magnolia (some species), and olive trees all hold their leaves through winter. In tropical regions, most trees are evergreen because there's no cold season to trigger dormancy. The U.S. Forest Service manages roughly 193 million acres of national forests containing both deciduous and evergreen species across every climate zone in the country.
Then there are the oddballs. Larches and tamaracks are deciduous conifers - they have needles like a pine tree but drop them every fall, turning gold before going bare. Ginkgo is another unusual case: it's technically neither a conifer nor a flowering tree. It belongs to its own ancient division of plants and is the only surviving member of a lineage that dates back 270 million years, making it one of the oldest living tree species on Earth.
Trees by Size: From Understory to Canopy Giants
Tree species vary enormously in height. At the smaller end, dogwoods top out around 35 feet and hawthorns at about 30 feet. These understory trees thrive in the shade of taller species and are popular in landscaping because they fit in residential yards. Redbud is another compact species - rarely exceeding 30 feet - and it's prized for its early spring flowers that bloom directly on the branches before any leaves appear.
Mid-size trees in the 50 to 100 foot range make up the backbone of most temperate forests. Maples, oaks, hickories, ashes, beeches, and elms all fall in this category. A mature sugar maple typically reaches 80 feet, and a white oak can hit 100 feet with a crown spread nearly as wide. These are the trees that line streets, shade parks, and form the canopy in forests across the eastern United States and Europe.
At the extreme end, coast redwoods hold the record as the tallest trees on Earth. The tallest known specimen, a redwood named Hyperion in northern California, stands at 380.3 feet - taller than the Statue of Liberty including its pedestal. Giant sequoias are the most massive trees by total volume, with General Sherman containing an estimated 52,500 cubic feet of wood. According to the National Park Service, no other living organism on Earth matches the giant sequoia in total bulk.
Botanical Families and What They Tell You
Knowing a tree's botanical family gives you instant clues about its characteristics. The Fagaceae family (beech, chestnut, oak) produces nuts as fruit - acorns from oaks, chestnuts from chestnuts, and beechnuts from beeches. The Juglandaceae family (walnut, hickory, pecan) also produces edible nuts, and all of its members have compound leaves with multiple leaflets on a single stem.
The Pinaceae family is the largest family of conifers and includes pines, spruces, firs, hemlocks, larches, and cedars. These trees dominate the boreal forests that wrap around the northern latitudes of North America, Europe, and Asia. They share key traits: needle-like leaves, seed-bearing cones, and resinous wood. The Salicaceae family connects willows, poplars, aspens, and cottonwoods - all fast-growing, water-loving trees that colonize riverbanks and disturbed ground.
The Rosaceae family, better known for roses and stone fruits, includes several tree species: cherry and hawthorn among them. Cherry trees in the Rosaceae family are the same genus (Prunus) as peach, plum, and almond trees. Washington D.C.'s famous cherry blossoms come from Japanese flowering cherry trees (Prunus serrulata), originally a gift from Japan in 1912.
Trees and Human History
Trees have shaped human civilization in ways that are easy to overlook. Oak wood built the ships that carried European explorers across the Atlantic. Teak built the trading vessels of Southeast Asia because its natural oils resist rot and marine borers. Mahogany became the defining material of 18th-century English and American furniture, so sought-after that entire Caribbean forests were logged to supply the demand. The white pine's tall, straight trunks were so valuable as ship masts that the British Crown marked the best specimens with a broad arrow, claiming them for the Royal Navy - a policy that infuriated American colonists and helped fuel resentment leading to the Revolution.
Certain trees carry deep cultural and symbolic weight. The olive tree has been cultivated around the Mediterranean for at least 6,000 years, and olive branches symbolize peace across multiple cultures. Yew trees, which can live for thousands of years, stand in churchyards throughout England and Wales - some predating the churches next to them by centuries. The ginkgo tree, called a "living fossil," survived the atomic bombing of Hiroshima: several ginkgo trees within a mile of ground zero sprouted new growth the following spring, and they're still alive today.
In North America, the American chestnut once dominated eastern forests. An estimated four billion chestnut trees stretched from Maine to Georgia before a fungal blight introduced around 1904 wiped out virtually every mature specimen within 50 years. It was one of the worst ecological disasters in recorded history. The American Chestnut Foundation has spent decades trying to breed a blight-resistant hybrid, and recent genetic engineering breakthroughs are bringing the species closer to a real comeback.
