Genus: Acer
Family: Aceraceae

Maples are deciduous, broadleaved plants that range from shrubs to large trees. Most have palmate leaves and winged seeds known as "samaras."

There are more than 100 different species of maples, and you can find 11 of them represented on the Reed campus, including Vine Maple and Bigleaf Maple, which are both native to Oregon.

Acer campestre
Hedge Maple

A deciduous tree, it is slow growing to 70 feet, but more often found at about 30 feet. Leaves are 3-5 lobed, 2-4 inches wide, dull green above, and they turn yellow in the fall. A good street tree that adapts well to drought, it is a native of Europe and western Asia.

Acer circinatum
Vine Maple

Schoolchildren in Oregon learn to recognize this maple by spelling out its name on the nine lobes of a leaf. Vine maples are often multi-trunked and in woodland habitat they can spread up to 20 feet, forming dense thickets. Red maple seeds (samaras) develop in spring and the leaves turn soft gold or chartreuse in the fall. This is a common plant to find in moist woods and along stream banks throughout the Pacific Northwest. We have identified only a few trees on the maps, but it is a common shrub on the Reed campus.

Acer davidii
David's Maple

David's Maple is an unusual ornamental tree that is native to central China. The leaves are oval-shaped (similar to the leaves of an alder) and the bark is shiny green.

Acer griseum
Paperbark Maple

Another ornamental maple from China, the paperbark maple gets its name from the thin red bark that peels away from the trunk in sheets. It has showy winged seeds (samaras) and bright red foliage.

Acer macrophyllum
Bigleaf Maple

Also known as the Oregon Maple, it has the largest leaves (15 inches across) of all maples. It is abundant in western Oregon and is distinguished by its beautiful autumn colors of yellow, gold, and copper. It can become a massive, beautiful tree, with nice spring blossoms.

(Most Japanese maples are too small to be shown on our maps, but they're a common shrub around campus.)

Acer platanoides
Norway Maple

A deciduous tree native to Europe and the Near East, it has dense foliage and reaches to 60-70 feet. Leaves are 5-lobed, 3-5 inches wide, and are deep green. They turn a bright yellow in the fall, and showy clusters of small, greenish-yellow flowers appear in early spring. This tree is very common on the Reed campus.

Acer pseudoplatanus
Sycamore Maple

This deciduous tree is native to Europe and western Asia. It can attain a height of 100 feet. Leaves are 3-5 inches wide, 5-lobed, thick, prominently veined, dark green above, pale below. The trunk has a scaly bark. This tree does not become colorful in the fall. Sycamore maples are common landscaping trees but they can be invasive in wetland areas and they appear to be moving into the Reed canyon.

Acer rubrum
Red Maple

A deciduous tree that is native to the eastern U.S. but very popular in the Pacific Northwest, it is fast growing and can reach a height of 120 feet in the wild. It displays small, attractive red flowers that bloom before the leaves appear.

The Red Sunset Maple, a cultivar noted for its bright red leaves in the fall, is pyramidal in shape and often grows to 60 feet in height. The leaves are 3-lobed, with short, broad lobes 2-6 inches long. This tree is widely planted in the parking lots on campus.

Acer saccharinum
Silver Maple

Native to eastern North America, this maple can become an enormous tree, attaining a height of 120 feet. Its leaves are 5-lobed, pointy, and silvery colored on the underside, hence the name.

Acer saccharum
Sugar Maple

This tree is native to the northeastern United States and to Canada (where it's the leaf shown on the flag). It's a colorful maple in the fall and it's the source of maple sugar. It can slowly reach an ultimate height of 120 feet.
