The Eddy Arboretum is located at the Institute of Forest Genetics in the Sierra Nevada near Placerville, in El Dorado County, eastern California.
The arboretum contains what is claimed to be the best-documented collection of native and exotic pines in the world, in addition to many other native and exotic conifers.
78 pine species, 24 fir species, and many other conifer species are growing on the arboretum's grounds. Some species collections sample a wide range of genetic diversity, such as the native California conifers Pinus lambertiana and Pinus coulteri .
The Arboretum's first plantings were made in 1926. Because genetic diversity is the raw material for breeding, the Arboretum assembled as many pine species and varieties as possible. The origins of individual seeds were recorded, often mapping the location of each parent tree.
The Eddy Arboretum is part of the Pacific Southwest Research Station of the United States Forest Service. It is open to the public during business hours, excluding weekends and holidays.

Pinus radiata, the Monterey pine, insignis pine or radiata pine, is a species of pine native to the Central Coast of California and Mexico. It is an evergreen conifer in the family Pinaceae.

The Klamath Mountains are a rugged and lightly populated mountain range in northwestern California and southwestern Oregon in the western United States. As a mountain system within both the greater Pacific Coast Ranges and the California Coast Ranges, the Klamath Mountains have a varied geology, with substantial areas of serpentinite and marble, and a climate characterized by moderately cold winters with very heavy snowfall and warm, very dry summers with limited rainfall, especially in the south. As a consequence of the geology and soil types, the mountains harbor several endemic or near-endemic trees, forming one of the largest collections of conifers in the world. The mountains are also home to a diverse array of fish and animal species, including black bears, large cats, owls, eagles, and several species of Pacific salmon. Millions of acres in the mountains are managed by the United States Forest Service. The northernmost and largest sub-range of the Klamath Mountains are the Siskiyou Mountains.
Pinus mugo, known as bog pine, creeping pine, dwarf mountain pine, mugo pine, mountain pine, scrub mountain pine, or Swiss mountain pine, is a species of conifer, native to high elevation habitats from southwestern to Central Europe and Southeast Europe.
Pinus peuce is a species of pine native to the mountains of Macedonia, Bulgaria, Albania, Montenegro, Kosovo, the extreme southwest of Serbia, and the extreme north of Greece, growing typically at (600-) 1,000-2,200 (-2,300) m altitude. It often reaches the alpine tree line in this area. The mature size is up to 35–40 m height, and 1.5 m trunk diameter. However, the height of the tree diminishes strongly near the upper forest limit and may even obtain shrub sizes.
Pinus contorta, with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine, but is rare in lowland rain forests. Like all pines, it is an evergreen conifer.
Pinus echinata, the shortleaf pine, is a species of pine native to the southeastern United States.
The Coulter pine or big-cone pine, Pinus coulteri, is a native of the coastal mountains of Southern California in the United States and northern Baja California in Mexico. Isolated groves are found as far north as Clearlake, California on the flanks of Mt. Konocti and Black Diamond Mines Regional Preserve. It is named after Thomas Coulter, an Irish botanist and physician. The Coulter pine produces the heaviest cone of any pine tree, up to 5 kg (11 lb) and among conifers is exceeded only by the cones of Araucaria bidwillii.
Pinus ponderosa, commonly known as the ponderosa pine, bull pine, blackjack pine, western yellow-pine, or filipinus pine is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America.
The stone pine, botanical name Pinus pinea, also known as the Italian stone pine, Mediterranean stone pine, umbrella pine and parasol pine, is a tree from the pine family (Pinaceae). The tree is native to the Mediterranean region, occurring in Southern Europe and the Levant. The species was introduced into North Africa millennia ago, and is also naturalized in the Canary Islands, South Africa and New South Wales.
Pinus brutia, commonly known as the Turkish pine, is a species of pine native to the eastern Mediterranean region. The bulk of its range is in Turkey.
The San Francisco Botanical Garden at Strybing Arboretum is located in San Francisco's Golden Gate Park. Its 55 acres represents nearly 9,000 different kinds of plants from around the world, with particular focus on Magnolia species, high elevation palms, conifers, and cloud forest species from Central America, South America and Southeast Asia.
The Arnold Arboretum of Harvard University is a botanical research institution and free public park, located in the Jamaica Plain and Roslindale neighborhoods of Boston, Massachusetts. Established in 1872, it is the oldest public arboretum in North America. The landscape was designed by Charles Sprague Sargent and Frederick Law Olmsted and is the second largest "link" in the Emerald Necklace. The Arnold Arboretum's collection of temperate trees, shrubs, and vines has a particular emphasis on the plants of the eastern United States and eastern Asia, where arboretum staff and colleagues are actively sourcing new material on plant collecting expeditions. The arboretum supports research in its landscape and in its Weld Hill Research Building.
The Bartlett Arboretum and Gardens in Stamford, Connecticut, contains 93 acres of parkland, gardens, landscapes, and hiking trails that focus on the regional plants, ecology and character of Southwestern New England. The Arboretum is open and accessible to the public every day of the year and is located at 151 Brookdale Road.

The Huron River separates a northern section of the arboretum's floodplain woods; the railroad marks the northern border.
The Plant Collections Network (PCN) is a group of North American botanical gardens and arboreta that coordinates a continent-wide approach to plant germplasm preservation, and promotes excellence in plant collections management. The program is administered by the American Public Gardens Association from its headquarters in Kennett Square, Pennsylvania, in collaboration with the USDA Agricultural Research Service.
The Tokai Arboretum was the first large-scale silviculture experimental station in Cape Town, South Africa. The area of the main Arboretum, at Tokai Park, is 14 ha. Several adjacent compartments extend the area to 26 ha. The Arboretum was declared a National Monument in 1985, on its 100th anniversary. It contains stands of Eucalyptus and other trees from the original silviculture experiments in South Africa. In the 1990s a Gondwana Garden was created to display the plants typical of the Cape 100 million years ago.
