While it can make a good large shade tree in the right circumstances, this is not a tree that is very tolerant of urban conditions. Needle-like leaves may be long or scale-like, each typical of a certain type of tree. Spruce have needles attached by short stems that give the older branches a rough texture. The upper side of the leaf is dark green in mid summer. s n r n ) n ) ns - pe. Sugar and black maple are particularly attractive as sugartrees because of their high sap sugar content and the late date at which they begin growth in the spring. endstream
It is most easily identified by the opposite paired arrangement of its leaves and branches and its 3lobed leaf with coarse teeth. Note first whether your plant has needle-like leaves like a pine or broad leaves like a maple or holly. You can compare them in the photos I've attached. Similar to sugar maple with, perhaps, a slightly larger seed. To make maple tree identification a little easier, let’s begin by dividing them into two main groups: hard and soft maples. Notice whether the young trunk is inclined to branch low or seems to have a strong main stem, a leader. Thanks so much Kristena. 5-7 inches wide; deeply clefted; 5-lobed with the sides of the terminal lobe diverging toward the tip; light green upper surface and a silvery white underside; leaf margin with fine teeth (but not the inner edges of the sinuses). The bark is smooth and light gray on young- and intermediate-aged stems, while mature bark is dark gray and rough. Its rapid growth and ability to thrive on a wide variety of sites have resulted in its widespread planting as ornamental and street trees which are often tapped as part of a sugaring operation. Sugar and black maples are found on a variety of soils and site conditions, but neither tolerates excessively wet or dry sites, and both grow best on moist, deep, well-drained soils. Five common species are shown here. . Healthy sugar and black maple trees growing in overstocked uneven-aged or even-aged stands can be expected to achieve tapable size in 40 to 60 years, depending on overall site quality. The sap of Norway maple is not commonly used to produce maple syrup. Both species are relatively long lived, capable of living well beyond 200 years, with trunk diameters greater than 30 inches and heights greater than 100 feet. Consult a map or chart to determine natural native maple varieties in your area. Thinning or release cutting dramatically reduces this age-to-tapable-size. If your seedling has broad leaves, notice whether they seem thin (probably deciduous), or thick and waxy (probably evergreen). Botanists have many terms for leaf shapes, from obovate, tear-drop shaped, to flabellate, fan-like. The following is used with the gracious permission of Ohio State University. Note first whether your plant has needle-like leaves like a pine or broad leaves like a maple or holly. Compare the leaves of the tree seed sprouts to the leaves of existing trees in the neighborhood. If you see a seedling in your garden that looks substantial enough to be a tree, you might wonder what it is and whether it would be worth transplanting. There are two great websites that can help, though: Virgina Tech, and Maple-trees.com. Young trees up to 4-8 inches with smooth gray bark. One of the most important characteristics of leaves is the way they are arranged on a stem. The leaf has 5 (or 7) lobes with small teeth. A somewhat shiny, brownish, slender, relatively smooth twig with. Because of the wide variety of sites on which red maple will grow, it is found growing naturally in pure stands and with an enormous variety of other tree species ranging from gray birch and paper birch, to yellow poplar and black cherry, and including sugar and black maple. Fruits mature in fall. Identifying a tree as a sugar or black maple (Table 3.2, Figure 3.2 & 3.3) is easily done from the leaves by observing 5-lobed leaves, the paired opposite attachment of the leaves along the stem and the lack of teeth along the leaf margin; from the bark of older trees by observing the long plates that remain attached on one side; from the twigs by observing the opposite arrangement of buds and the relatively long, pointed, brownish terminal bud; and from the seed by observing its horseshoe shape and size. It is important to emphasize that good, high-quality maple syrup can be made from red maple sap. Cluster of maple seedlings hanging on a branch Bright fall foliage of a red maple tree in Maine. Mountain maple is essentially a shrub. Mature trees commonly average between 20 and 30 inches in diameter and 60 and 90 feet tall. For example, the sugar maple grows in the Northeast United States and Southern Canada, while the vine maple and bigleaf maple both grow on the Pacific coast of both the United States and Canada. The leaf has 5 lobes, each with large teeth. Some are placed in twos, directly opposite each other. To do this, begin by counting lobes of leaves. The first leaves any seed sends up are called cotyledons and they are different from the ordinary leaves in shape and size. The leaf has 5 main lobes. Notice both the shape and the texture of the leaves. It is most easily identified by the opposite paired arrangement of its leaves and branches, its 3-lobed leaf with fine teeth on the margin, and striping on the branches and young trunks. Because of its fast growth rate, however, mature trees can achieve diameters in excess of 3 feet and heights in excess of 100 feet. This is the geographic area of greatest abundance of sugar maple (Acer saccharum) and black maple (Acer nigrum), the two most preferred and most commonly tapped maple species. On way to work, I pass a row of gorgeous trees in the fall. Leaves turn red in autumn. Basic ID (Abies spp): Larger seedling (2-4 cm when germinated), 4-7 cotyledons with characteristic curved shape, tips blunt to rounded to notched (rarely acute, except possibly for A. procera ). Japanese Maple Acer palmatum. A fourth maple species, silver maple (Acer saccharinum), is sometimes tapped, particularly in roadside operations, and is often confused with red maple. One notable example is A Guide to Seedling Identification for 25 onifers of the Pacific Northwest by forest ecologist Jerry Franklin.1 Nevertheless, seedling identification resources for the Pacific Northwest could Black and sugar maples begin growth later in the spring than red or silver maple. Contact your local county extension service for information about maples grown in your area. The size will be smaller and the color may be lighter, but infant tree leaves have the same characteristics as their parents. All maple leaves form a central stem with veins that branch off and between three and seven main branches. Your seedling may be too small to have many branches, but if it does, whether the branches are alternate or opposite is important.
