Red Maple leaves are arranged in pairs ( opposite), are generally 3-4″ long and slightly less wide than they are long. The branching is opposite, as in it occurs in pairs. The scales can resemble tracks, or be irregular. The bark on mature trees is gray and scaly. The Red Maple Tree is native to Eastern North America, grows up to 80′ tall with a 3′ diameter trunk. Female flowers that are fertilized will produce pairs of winged seeds (samaras) that are wide, almost 180 degrees between them.

Individual flowers are small, 1/4″ to 3/8″ of an inch (6-9mm). Norway Maple will bloom small yellow flowers in clusters that are 3″ diameter overall that are visually quite different from native Maple Trees. There are infrequent teeth/serration on the lobes ( dentate). Like the overall size, the individual lobes are wider than they are tall with sharply pointed tips. They are paired ( opposite), dark green color, hairless, and usually with 5 palmate lobes. Leaves are fairly large, 3-6″ long and they will be wider than they are long. The ridges can cross back on itself, similar to Tulip Poplar or Ash trees. Mature bark is dark gray ridges with brown furrows. If you see white sap, your identification is complete.īut, botanically, mature Norway Maples can grow up to 80′ tall with a 30″ trunk diameter. If you see one, rip off a leaf, and look for sap that flows immediately. It can be difficult to differentiate Norway Maple from other Maples based on leaf shape, but there is one telltale sign – the leaves excrete a white sap when pulled from the tree. And unfortunately, was/is a popular choice for suburban, urban, and commercial landscaping due to it’s nice shape and beautiful fall colors. Norway Maple is an invasive species from Europe. Norway Maple ( Acer platanoides) Identification Initially green, they will turn brown and often stay attached to the tree through Winter. They tend to have no angle between them, and are attached by a 1-2″ stem, which is unique. The winged seeds (samaras) will form after pollination and are roughly 1-1.5″ long (2.5-4 cm). Female flowers will be red-green with a single pistil and forked style. Male flowers will have small green flowers with about 5 large red stamens. The edges will be serrated with large teeth ( dentate).īox Elder will bloom either male or female flowers in Spring. Leaves are a lighter green color and are attached by short stems to the branches. And individual leaflets are 2-4″ long and will have several lobes. These opposite leaves are compound, and are odd-pinnate with 3-7 leaflets. Leaves and branches are paired ( opposite) on the tree. Older mature trees will have a rough furrowed bark. The bark of young trees and branches is green & smooth while the primary trunk will turn gray. It often is found along fence lines or along forest edges where it will branch abundantly. The Boxelder tree is a mid-sized tree up to 60′ tall and a trunk that can grow 2-3′ diameter (60-90 cm). It will help you differentiate the leaves, bark, flower, and seed of all common Maple species native to North America, as well as some non-natives that are now invasive or frequently used in landscaping.īoxelder Tree ( Acer negundo) Identificationīoxelder tree leaves do not resemble a typical ‘Maple’ leaf, but I’ve included them in this Maple Identification Guide as they are of the same genus ( Acer), and they produce seed in a similar manner (samaras). This guide is to help you identify all major species of Maple Trees in North America, with a focus on those Maples native to the Eastern half. Also, all images should be directly linked to the media file for higher resolution. From these large infographics, you can identify the likely candidates of your tree, and then jump to the more detailed species descriptions.

I will include comparisons of the leaves and bark for most major Maple species native to Eastern North America, as well as a couple non-native species that are either invasive or frequently encountered. So, I created this guide to help you identify the most common Maple Trees in North America.

Red Maple tree (right) showing fall color. The bark, leaves, flowers, and winged seeds can all get confusing… On the left is invasive Norway Maple, which doesn’t change color (to yellow) until later. But many Maple Trees can look alike and be a challenge to identify. In the wild there are around 15 native Maple species one may encounter depending on what part of the country you find yourself in.

Maple Trees are one of the most popular and commonly used trees used for landscaping in the United States.
