Of the dozens of maple trees that exist in the world, 14 varieties are common in North America. Some trees have pointed buds, some are rounded, others are so small you can hardly see them. 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. Despite the importance of early life stages to the survival, growth, and development of plants, little is known about the morphology of seedlings. 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. Maple Tree Identification. Striped maple (Acer pensylvanicum) and mountain maple (Acer spicatum) are two other native maples that are found growing within the commercial maple range (Figures 3.10 and 3.11). h�ܖmO9ǿ�_������*R�"= �q��/�V 2-6 inches wide; 3lobed (occasionally weakly 5-lobed); sharply V-shaped sinuses; small sharp teeth alongmargin. The problem with seedlings is that they lack flowers and fruit, the main features botanists used to classify plants. Leaves turn red in autumn. Both species have been planted extensively as roadside trees which are often tapped as part of a sugaring operation. The leaf has 5 (or 7) lobes with small teeth. In the United States, most maple species are best suited to USDA Zones 3-8, an area that covers most of the continental U.S. Because of its fast growth rate, however, mature trees can achieve diameters in excess of 3 feet and heights in excess of 100 feet. The leaf edges are smooth. The bark is smooth and light gray on young- and intermediate-aged stems, while mature bark is dark gray and rough. Although it develops best on moderately well-drained to well-drained, moist soils, it commonly grows in conditions ranging from dry ridges to swamps. by William M. Harlow, Elwood S. Harrar, and Fred M. White; Sycamore Acer pseudoplatanus.The leaf has 5 tooth-edged lobes. 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 If you have maple tree seed sprouts in your yard, identifying the variety can be an interesting puzzle. It does not respond well to compacted soils, road salts, or pollution. The commercial production of maple products in North America occurs primarily in the northeastern United States and southeastern Canada (Figure 3.1). What Is the Average Height of Adult Maple Trees? They have experts who can identify your maple tree seed sprouts and advise on how best to care for them. However, for sugaring, red maple does have three important weaknesses. Fruits mature in fall. Because sugar and black maple resume growth later than red or silver maple, sap may be collected later in the spring. Likewise, maple species can vary from shrub-size Japanese maples to sugar maples that reach 75 ft (23 m) in height and 50 ft (15 m) in canopy spread, so choose a species that suits your available space. h�bbd```b``V�� �)D�l���$ӆ,y���+�3v�_ik�?��20Ґ�t�� �� First, the sap sugar content of red maple will be less, on the average, than that of nearby comparable sugar or black maples, perhaps by 1/2 percent or more. Seedling guides for native plants are rare, but would be useful for plant ecologists and habitat restoration projects. Note also the shape of the dormant buds along the stem. Black maple, on the other hand, occupies a much smaller natural range (Figure 3.7). This maple is the first choice for those seeking to make maple syrup, as the sap contains a larger percentage of plant sugars than with any other maple species. Note: There are thousands of species of maple trees in the world—we cannot easily identify maple species over the phone or via email. Compared to other maples, sugar maples color unevenly in the fall; sometimes yellows, oranges, and reds are all seen at the same time. Red Maple Tree On good sites with little competition from other trees, silver maple diameter growth may approach 1/2 inch per year (rates as high as 1 inch per year have been recorded). Geographic ranges adapted from Textbook of Dendrology, 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. The Norway Maple differs from the Field Maple and Sycamore in that its lobes and teeth have finely pointed tips. The sugar maple has bright green leaves with five lobes that have no jagged edges, while the vine maple leaves are almost circular with seven to nine lobes, and the bigleaf maple is said to be shaped like a giant's hand. Copyright Leaf Group Ltd. // Leaf Group Lifestyle. MMPA is a non-profit organization dedicated to the preservation and promotion of maple sugaring in Massachusetts. Similar to sugar maple but usually 3-lobed (sometimes five); often appears to be drooping; often with a thicker leaf and lear stem (petiole) than sugar maple; usually with two winglike or leaflike growths at the base of the petiole (stipules). While seed sprouts don't have any identifying bark, they produce leaves that are identical to adult trees of the same variety. . Mountain maple is essentially a shrub. Contact your local county extension service for information about maples grown in your area. Some are placed in twos, directly opposite each other. Japanese Maple Acer palmatum. Needle-like leaves may be long or scale-like, each typical of a certain type of tree. 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. The leaf has 5 lobes, each with large teeth. The 3 most popular type of maple trees are Maple Sugar, Red maple and Japanese Maple. Sugar and black maple both grow in the shade of other trees (they are shade tolerant), and trees of many different ages (sizes) are often found in a forest. Is there an easy way to distinguish between a Crimson King maple seedling and other varieties of maple? Compared to sugar and black maple, red maple is a relatively short-lived tree, rarely living longer than 150 years.
