red maple leaf identification

December 2, 2020

Like several other maples, its low root system can be invasive and it makes a poor choice for plantings near paving. While many believe that it is replacing historically dominant tree species in the eastern United States such as sugar maples, beeches, oaks, hemlocks and pines, red maple will only dominate young forests prone to natural or human disturbance. It has the largest continuous range along the North American Atlantic Coast of any tree that occurs in Florida. Early winter, forests across the northwestern mountainous region are dyed the yellowish-red of maple leaves. [6] They ripen from April through early June, before even the leaf development is altogether complete. They are typically 5–10 cm (2–4 in) long and wide with 3-5 palmate lobes with a serrated margin. Not all red maple trees have red leaves in the fall, so buy a nursery plant in the fall to be certain. However, it is nonetheless common in mountainous areas on relatively dry ridges, as well as on both the south and west sides of upper slopes. 432 416 93. The red maple is used as a food source by several forms of wildlife. I have found previous posts which might contain the answer. It is used commercially on a small scale for maple syrup production as well as for its medium to high quality lumber. The red maple can be considered weedy or even invasive in young, highly disturbed forests, especially frequently logged forests. When it comes to fall color, sugar maples are at the top of the list. A. rubrum is not present in most of the Prairie Peninsula of the northern Midwest (although it is found in Ohio), the coastal prairie in southern Louisiana and southeastern Texas and the swamp prairie of the Florida Everglades. Over most of its range, red maple is adaptable to a very wide range of site conditions, perhaps more so than any other tree in eastern North America. World Checklist of Selected Plant Families, "Ten Most Common Trees in the United States", "Eastern Forests Change Color As Red Maples Proliferate", Southern Research Station (www.srs.fs.fed.us), "RHS Plant Selector Acer rubrum 'October Glory' AGM / RHS Gardening", "Autumn's Harbinger: Acer rubrum 'Schlesingeri, "Heating With Wood: Species Characteristics and Volumes". In good light and moisture conditions, the seedlings can grow 30 cm (0.98 ft) in their first year and up to 60 cm (2.0 ft) each year for the next few years, making it a fast grower.[8]. Finally, disease epidemics have greatly reduced the population of elms and chestnuts in the forests of the US. And although red maple (Acer rubrum) is most commonly associated with poisoning in horses, the wilted leaves of silver maple (Acer saccharinum) and sugar maple (Acer saccharum) are also potentially toxic to horses, so should be treated similarly. They appear in late winter to early spring, from December[9] to May depending on elevation and latitude, usually before the leaves. Many cultivars of the Freeman maple are also grown widely. Early winter, forests across the northwestern mountainous region are dyed the yellowish-red of maple leaves. The tree's thin bark is easily damaged from ice and storms, animals, and when used in landscaping, being struck by flying debris from lawn mowers, allowing fungi to penetrate and cause heart rot. The buds are usually blunt and greenish to reddish in color, generally with several loose scales. (zones 3-9) Consuming .03% of dry wilted leaves … Several Lepidoptera (butterflies and moths) utilize the leaves as food, including larvae of the rosy maple moth (Dryocampa rubicunda); see List of Lepidoptera that feed on maples. Another excellent method of identification is to examine the stem of the red maple leaf, also known as the stalk or petiole. Maple Leaf Fall Leave. They also would brew tea from the inner bark to treat coughs and diarrhea. Thus, high grades of wood from the red maple can be substituted for hard maple, particularly when it comes to making stain/paint-grade furniture. The fall colors of red maple are most spectacular in the northern part of its range where climates are cooler. Return to Trees and Shrubs Agent Articles. Yellow leaves may predominate in ginkgos, tulip poplar, beeches, buckeyes, and hickories. Another possible cause of yellowing leaves is root and crown rot. October Glory is an excellent choice for a fast growing small tree. The allergenic potential of red maples varies widely based on the cultivar. Also, the decline of American elm and American chestnut due to introduced diseases has contributed to its spread. [8], Native Americans used red maple bark as a wash for inflamed eyes and cataracts, and as a remedy for hives and muscular aches. In this context, the term "soft" is more comparative, than descriptive; i.e., "soft maple", while softer than its harder cousin, sugar maple (A. saccharum), is still a fairly hard wood, being comparable to black cherry (Prunus serotina) in this regard. Incidentally, in a research setting, horses fed fresh green leaves from red maple trees Treatment is limited and can include the use of methylene blue or mineral oil and activated carbon in order to stop further absorption of the toxin into the stomach, as well as blood transfusions, fluid support, diuretics, and anti-oxidants such as Vitamin C. About 50% to 75% of affected horses die or are euthanized as a result. In Florida, at the extreme south of the red maple's range, it is limited exclusively to swamplands. It is a medium to large sized tree, reaching heights of 27 to 38 metres (90 to 120 ft) and exceptionally over 41 metres (135 feet) in the southern Appalachians where conditions favor its growth. These … Maple trees shed their leaves near the top of Nam Kang Ho Tao, which connects Lai Chau to Lao Cai. As a result of such variation, there is much genetic potential for breeding programs with a goal of producing red maples for cultivation. [6] Generally the crown is irregularly ovoid with ascending whip-like curved shoots. The leaf edges have many sharp “teeth.” red maple tree in Maine image by Jorge Moro from Fotolia.com It only contributed minimally to old growth upland forests, and would only form same-species stands in riparian zones. [7], Red maple is a good choice of a tree for urban areas when there is ample room for its root system. [14] It grows on glaciated as well as unglaciated soils derived from the following rocks: granite, gneiss, schist, sandstone, shale, slate, conglomerate, quartzite, and limestone. [11] The petals are lineal to oblong in shape and are pubescent. Buds conspicuous, plump, rounded, and red; side buds as large as terminal buds, and angled outward. Flowers dangling, yellow-green. [5], Though A. rubrum is usually easy to identify, it is highly changeable in morphological characteristics. Certain specific weather conditions can cause leaves to exhibit this behavior before fall, leading many gardeners to erroneously believe the tree is sick when it is simply anticipating fall weather. The leaves of red maple trees are three-five-lobed and green, with bright red stems and silver-white undersides. Furthermore, it is common in swampy areas, along the banks of slow moving streams, as well as on poorly drained flats and depressions. As with all North American maple trees, they are deciduous and arranged oppositely on the twig. Is it a maple tree? Grows to 40' to 60', 40' spread. Identifying a tree as a red maple (Table 3.2, Figure 3.4) is done from the leaves by observing the 3 lobes (occasionally 5), the paired opposite arrangement of the leaves and the small teeth along the margin; from the bark of older trees by the presence of the scaly plates; from the twig by observing the paired opposite arrangement of the buds, the relatively short, blunt, rounded, red terminal bud and the … Flowers are also red. 248 170 35. However, one- to four-year-old seedlings are common under dense canopy. They make excellent shade trees for large backyards, while preferring full-sun exposure. Green stems turn red in winter, new leaves are red-tinged, turning to green. This not only decreases oxygen delivery to all tissues, but also leads to the production of methemoglobin, which can further damage the kidneys. An example is the Bluegrass region of Kentucky, where red maple is not found in the dominant open plains, but is present along streams. [8] The density of the tree in many of these areas has increased 6- to 7-fold, and this trend seems to be continuing, all of which is due to human factors, mainly continued heavy logging and a recent trend of young, shrubby forests recovering from past human disturbances. Identify the red maple tree by its leaves, which are 2 to 6 inches wide with three to five shallow lobes. Pioneers made cinnamon-brown and black dyes from a bark extract, and iron sulphate could be added to the tannin from red maple bark in order to make ink.[27]. Leaves: The leaves of the Red Maple are very roughly toothed with 3-5 shallow lobes. [citation needed], Red maple is also used for the production of maple syrup, though the hard maples Acer saccharum (sugar maple) and Acer nigrum (black maple) are more commonly utilized. The leaf scars on the twig are V-shaped and contain 3 bundle scars. If the leaf margin, or edge, of your maple's leaves appear serrated, it is probably a red maple. Maple Maple Leaves. In a mature or old growth northern hardwood forest, red maple only has a sparse presence, while shade tolerant trees such as sugar maples, beeches, and hemlocks thrive. They are borne on long slender stems and are variable in color from light brown to reddish. Because it can grow on a variety of substrates, has a high pH tolerance, and grows in both shade and sun, A. rubrum is a prolific seed producer and highly adaptable, often dominating disturbed sites. [6], The flowers are generally unisexual, with male and female flowers appearing in separate sessile clusters, though they are sometimes also bisexual. Flowers while leafing out. In total it ranges 2,600 km (1,600 mi) from north to south. It grows well from sea level to about 900 m (3,000 ft). Red maple dominates such sites, but largely disappears until it only has a sparse presence by the time a forest is mature. While many types of tree prefer a south- or north-facing aspect, the red maple does not appear to have a preference. The trunk diameter often ranges from 46 to 88 cm (18 to 35 in); depending on the growing conditions, however, open grown trees can attain diameters of up to 153 centimetres (60 in). In northern Michigan and New England, the tree is found on the tops of ridges, sandy or rocky upland and otherwise dry soils, as well as in nearly pure stands on moist soils and the edges of swamps. In winter, buds are easily distinguished. Acer rubrum, the red maple, also known as swamp, water or soft maple, is one of the most common and widespread deciduous trees of eastern and central North America. The absence of red maple from the Prairie Peninsula is most likely due to the tree's poor tolerance of wildfires. [13] Here the red maple is not present in the bottom land forests of the Grain Belt, despite the fact it is common in similar habitats and species associations both to the north and south of this area. 172 241 17. Distinctive Bark. In the Northeastern US, red maple can be a climax forest species in certain locations, but will eventually give way to sugar maple. The roots are primarily horizontal, however, forming in the upper 25 cm (9.8 in) of the ground. Fast growing and tolerant of many soils. Buds more discrete, sharply pointed, and brown. In areas disturbed by humans where the species thrives, it can reduce diversity, but in a mature forest it is not a dominant species; it only has a sparse presence and adds to the diversity and ecological structure of a forest. As fall approaches, Japanese red maple leaves turn brown, wilt and defoliate. The leaf stalks are usually red and are up to 10 cm (4 in) long. Seedlings are tallest in the north-central and east-central part of the range. The most abundant tree species in North America, and a habitat generalist, native to a wide range across the eastern part of the continent. Autumn Leaves Maple. Throughout maple leaf season, you'll be able to catch maple leaves … Every year the leaves become brown as well in the summer, as if they are dried or burned up. Find out about some of the most popular maple tree varieties in this article. The following cultivars are completely male and are highly allergenic, with an OPALS allergy scale rating of 8 or higher:[17], The following cultivars have an OPALS allergy scale rating of 3 or lower; they are completely female trees, and have low potential for causing allergies:[17], The leaves of red maple, especially when dead or wilted, are extremely toxic to horses. [8] The species is native to all regions of the United States east of the 95th meridian. [8], Acer rubrum does very well in a wide range of soil types, with varying textures, moisture, pH, and elevation, probably more so than any other forest tree in North America. It attracts squirrels, who eat its buds in the early spring, although squirrels prefer the larger buds of the silver maple. The tree itself is considered polygamodioecious, meaning some individuals are male, some female, and some monoecious. Toward its southern limit, 'Fireburst', 'Florida Flame', and 'Gulf Ember' are preferred. The leaves of the red maple offer the easiest way to distinguish it from its relatives. The tree likes Sun at the location and the soil should be loamy-sandy to loamy. [8] Red maple produces one of the smallest seeds of any of the maples. Among these features, however, it is best known for its brilliant deep scarlet foliage in autumn. The leaves can turn a characteristic brilliant red in autumn, but can also become yellow or orange on some individuals. Chlorosis can occur on very alkaline soils, though otherwise its pH tolerance is quite high. Red maple is most abundant in the Northeastern US, the Upper Peninsula of Michigan, and northeastern Wisconsin and is rare in the extreme west of its range and in the Southeastern US. During Autumn, leaves turn a bright red or an bright orange. However, the buds of red maple and other soft maples emerge much earlier in the spring than the sugar maple, and after sprouting chemical makeup of the sap changes, imparting an undesirable flavor to the syrup. The leaves are usually 9 to 11 centimetres (3 ⁄2 to 4 ⁄4 in) long on a full-grown tree. Due to their wide range, genetically the trees have adapted to the climatic differences. It can be found growing in swamps, on poor dry soils, and almost anywhere in between. [8], Red maple can grow in a variety of moist and dry biomes, from dry ridges and sunny, southwest-facing slopes to peat bogs and swamps. Fresh red maple leaves are not the problem. Types of Acer Maple Trees The sinuses are typically narrow, but the leaves can exhibit considerable variation. Acer rubrum is one of the first plants to flower in spring. In contrast, the leaves of the related silver maple, A. saccharinum, are much more deeply lobed, more sharply toothed and characteristically have 5 lobes. There are fungicides labelled to control Tar Spot on maple trees, but thorough coverage of all leaf surfaces is critical. Autumn Leaf Colorful. Autumn Background Color. However, the wood from Acer rubrum while being typically less expensive than hard maple, also has greater dimensional stability than that of A. saccharum, and also machines and stains easier. Red maple has a highly variable leaf shape, and some can look similar to sugar maple, but they are easily distinguished by serrations and the color of the leaf underside. The leaves are lobed and the flowers are red. Photo © Parks Canada / Parcs Canada / Cape Breton / Cap-Breton. … [8] Additionally, red maple is one of the most drought-tolerant species of maple in the Carolinas.[15]. Red maple lumber also contains a greater percentage of "curly" (aka "flame"/"fiddleback") figure, which is prized by musical instrument/custom furniture makers, as well as the veneer industry. It is also the state tree of Rhode Island. During the fall, Animal Crossing: New Horizons players will notice red Maple Leaves flying about. One of the things many maple tree owners see is that the leaves start producing black spots on them. The bark is a pale grey and smooth when the individual is young. Red maple has a paler, almost whitish shade of green on its undersides as opposed to the dull green above. The spots can also be small black pinpricks like a banana or mango that's going bad. Red Maple Trees: Common problems. Most of the Red Maple leaves are a light or a pale green to a whitish.

In most cases, the leaves will be enough to help you determine what kind of maple you have. A maple forest on the road to the top of Nhiu Co San Mountain, which is 2,965 meters above sea level and one of Vietnam’s 10 highest mountains, in Lao Cai Province. Autumn Leaves Maple. They appear in December and January in Florida, later in the northern part of its range. 279 300 41. Maples have a reputation for providing striking autumn colors, but their spring and summer colors in some cases identify them. Red maple is one of the first species to start stem elongation. While mainline forest trees continue to dominate mesic sites with rich soil, more marginal areas are increasingly being dominated by red maple. This being the case, red maple can only be tapped for syrup before the buds emerge, making the season very short. In the far south of its range, it is almost exclusively associated with swamps. The newly emerging leaves and red flowers and fruits signal that spring has come. Because the leaves of these species can look so similar, it can be hard to tell exactly what you are looking at. There is much more to identifying tree leaves than just by their shape. At first the twigs are green but later in the year they turn a red. Red Maple trees such as Autumn Blaze Maple or October Glory can have shades of orange and red. Many of its features, especially its leaves, are quite variable in form. [6] When five lobes are present, the three at the terminal end are larger than the other two near the base. The tree's range ends where the −40 °C (−40 °F) mean minimum isotherm begins, namely in southeastern Canada. The silver maple has a dull green shade on its upper side, but the underneath of the leaf takes on a silver-white hue. This vibrant maple boasts crimson fall leaves, reddish seed pods in early spring, small red flowers from March to May, and reddish stems during the winter. The most famous local trekking routes include the peaks of Pu Ta Leng in Lai Chau, Ta Xua in Yen Bai, the Hoang Lien Son range in Lao Cai, home to resort town Sapa and Fansipan - nicknamed "roof of Indochina", as well as Bach Moc Luong Tu, located between Lai Chau and Lao … The upper side of A. rubrum's leaf is light green and the underside is whitish and can be either glaucous or hairy. Samaras green with large round seeds; not yet formed when tree is leafing out. [12], The fruit is a samara 15 to 25 millimeters (5⁄8 to 1 in) long that grows in pairs with somewhat divergent wings at an angle of 50 to 60 degrees. Underside of mature leaves similar in color or only slightly lighter than top. Samaras bright red, usually well-formed when leaves are leafing out. [8], In several other locations, the tree is absent from large areas but still present in a few specific habitats. [7] The largest known living red maple is located near Armada, Michigan, at a height of 38.1 m (125 ft) and a bole circumference, at breast height, of 4.95 m (16 ft 3 in).[8]. The flowers are red with 5 small petals and a 5-lobed calyx, usually at the twig tips. [8] Red maple's western range stops with the Great Plains where conditions become too dry for it. Its flowers, petioles, twigs and seeds are all red to varying degrees. Red maple is a medium quality firewood,[28] possessing less heat energy, nominally 5.4 gigajoules per cubic metre (18.7 million British thermal units per cord) , Maple tree leaves: Red maple tree leaves are light green with white undersides. Red maple is mortally sensitive to salt, and a salt-affected red maple's leaves can yellow as the tree dies. This tree if sometimes confused with red-leaved cultivars of Norway maple. Though they eventually die if no light reaches them, they serve as a reservoir, waiting to fill any open area of the canopy above. It is the wilted green leaves from windfall, pruned limbs or after a heavy frost that can produce poisoning. Due to A. rubrum's very wide range, there is significant variation in hardiness, size, form, time of flushing, onset of dormancy, and other traits. Samaras are also distinctive. The buds form in fall and winter and are often visible from a distance due to their large size and reddish tint. A shade-tolerant deciduous tree of the northeast, often associated with climax communities on rich, mesic sites. Identification: Not to be confused with tar spot, these spots appear on a maple's leaves, are tan to brown in the center, and are violently red to purple around the edges. Forming an association with Arbuscular Mycorrhizal Fungi can help A. rubrum grow along city streets. Just like Cherry Blossom Petals, these Maple Leaves are used to … [18], Red maple's rapid growth, ease of transplanting, attractive form, and value for wildlife (in the eastern US) has made it one of the most extensively planted trees. The seeds are epigeal and tend to germinate in early summer soon after they are released, assuming a small amount of light, moisture, and sufficient temperatures are present. Red Maple Leaf Autumn. For this guide, we have chosen some of the trees commonly found on the trails at the Arboretum. than other hardwoods such as ash: 7.0 GJ/m3 (24 million British thermal units per cord), oak: 7.0 GJ/m3 (24 million British thermal units per cord), or birch: 6.1 GJ/m3 (21 million British thermal units per cord). Red maple frequently hybridizes with silver maple; the hybrid, known as Freeman's maple, Acer × freemanii, is intermediate between the parents. A. rubrum's high pH tolerance means that it can grow in a variety of places, and it is widespread along the eastern United States. The lateral buds are slightly stalked, and in addition there may be collateral buds present as well. Though A. rubrum is usually easy to identify, it is highly changeable in morphological characteristics. As a soft maple, the wood tends to shrink more during the drying process than with the hard maples. Examining the leaves more closely can help you identify them. In winter, buds are easily distinguished. If you happen to be in spring, try spotting some samaras on your tree. Fall color is deep red or yellow. A single tree between 5 and 20 cm (2.0 and 7.9 in) in diameter can produce between 12,000 and 91,000 seeds in a season. Dwarf shoots are present on many branches. 1,102 Free images of Red Maple Leaf. They are slow to establish, have poor branching structure and, most importantly, they are susceptible to long-term trunk injury or damage, which results in internal rot and decay. The ingestion of 700 grams (1.5 pounds) of leaves is considered toxic and 1.4 kilograms (3 pounds) is lethal. This Canadian maple tree natives are absolutely spectacular in autumn when their foliage turns to shades of red, orange, and yellow. Brings color to your landscape year-round. Red maple is able to increase its numbers significantly when associate trees are damaged by disease, cutting, or fire. It can be found from the south of Newfoundland, through Nova Scotia, New Brunswick and southern Quebec to the southwest west of Ontario, extreme southeastern Manitoba and northern Minnesota; southward through Wisconsin, Illinois, Missouri, eastern Oklahoma, and eastern Texas in its western range; and east to Florida. Abstract Autumn Bright. [8] Its ability to thrive in a large number of habitats is largely due to its ability to produce roots to suit its site from a young age. The toxin is unknown, but believed to be an oxidant because it damages red blood cells, causing acute oxidative hemolysis that inhibits the transport of oxygen. I also have a red maple (Acer palmatum) on the balcony in a pot. In parts of the Pacific Northwest, it is one of the most common introduced trees. [8] One of its associates, the black cherry (Prunus serotina), contains benzoic acid, which has been shown to be a potential allelopathic inhibitor of red maple growth. Are you looking for stunning FREE clips to use in your projects? [8], Acer rubrum is one of the most abundant and widespread trees in eastern North America. Trees on poorer sites often become malformed and scraggly. This will often be red or at least have a reddish tint to it on the front side. The pistillate flowers have one pistil formed from two fused carpels with a glabrous superior ovary and two long styles that protrude beyond the perianth. Due to its attractive fall foliage and pleasing form, it is often used as a shade tree for landscapes. One study found that 6 years after clearcutting a 3.4 hectares (8.4 acres) Oak-Hickory forest containing no red maples, the plot contained more than 2,200 red maple seedlings per hectare (900 per acre) taller than 1.4 m (4.6 ft). The vine maple usually has hints of red to go with the predominant green color of the leaf. Unlike sugar maples and silver maples, red maple leaves have serrated margins and the indention between the lobes is not deep. Tree Leaf Identification. [15] Fertilization has also been shown to significantly increase the seed yield for up to two years after application. [10] The red maple will begin blooming when it is about 8 years old, but it significantly varies between tree to tree: some trees may begin flowering when they are 4 years old. The twigs of the red maple are reddish in color and somewhat shiny with small lenticels. The U.S. Forest service recognizes it as the most abundant native tree in eastern North America. The leaves are usually 9 to 11 centimetres (3 1⁄2 to 4 1⁄4 in) long on a full-grown tree. There it is frequently found in many parks and yards. Samaras are also distinctive. After they reach maturity, the seeds are dispersed for a 1 to 2 week period from April through July. The trunk will remain free of branches until some distance up the tree on forest grown trees, while individuals grown in the open are shorter and thicker with a more rounded crown. It is a medium to large sized tree, reaching heights of 27 to 38 metres (90 to 120 ft) and exceptionally over 41 metres (135 feet) in the southern Appalachians where conditions favor its growth. Red maple has a highly variable leaf shape, and some can look similar to sugar maple, but they are easily distinguished by serrations and the color of the leaf underside. Treatment for Maple Leave Tar Spot. If the seeds are densely shaded, then germination commonly does not occur until the next spring. 96 118 3. The leaves are pale green and whitish on the undersides, turning bright red or orange in autumn. A tree 30 cm (0.98 ft) in diameter was shown to produce nearly a million seeds. Welcome to the University of Tennessee Arboretum Tree Identification Guide! [8] Under the proper conditions, the tree can sometimes switch from male to female, male to hermaphroditic, and hermaphroditic to female. The staminate flowers are sessile. Even if you keep your lawn free of infected leaves, the chance of a tree from “down the block” infecting your tree is always present. This species is in fact a vital part of forest regeneration in the same way that paper birch is. Like A. saccharum, the wood of red maple is close-grained, but its texture is softer, less dense, and has not as desirable an appearance, particularly under a clear finish. Most seedlings do not survive in closed forest canopy situations. Twigs: Most Red Maple twigs appear to be slender and glossy. In wet locations, red maple seedlings produce short taproots with long, well-developed lateral roots; while on dry sites, they develop long taproots with significantly shorter laterals. At the same time, they are tolerant of drought due to their ability to stop growing under dry conditions by then producing a second growth flush when conditions later improve, even if growth has stopped for 2 weeks.[8]. Sugar maple leaves can be a brilliant orange. The tree was introduced into the United Kingdom in 1656 and shortly thereafter entered cultivation. Name: Acer saccharum. Its popularity in cultivation stems from its vigorous habit, its attractive and early red flowers, and most importantly, its flaming red fall foliage. The seeds of Red maple are quite popular with squirrels and birds. [20], Red maples make vibrant and colorful bonsai, and have year around attractive features for display. Red maple is far more abundant today than when Europeans first arrived in North America. This is especially useful for making urban cultivars that require resistance from verticillium wilt, air pollution, and drought.[8]. The trunk diameter often ranges from 46 to 88 cm (18 to 35 in); depending on the growing conditions, however, open grown trees can attain diameter… A crop of seeds is generally produced every year with a bumper crop often occurring every second year. The staminate flowers contain between 4 and 12 stamens, often with 8. If you are in doubt, look at the bark of the tree to make a positive identification. Extensive use of red maple in landscaping has also contributed to the surge in the species' numbers as volunteer seedlings proliferate. Trees growing in a Zone 9 or 10 area such as Florida will usually die from cold damage if transferred up north, for instance to Canada, Maine, Vermont, New Hampshire and New York, even if the southern trees were planted with northern red maples. [4] The red maple ranges from southeastern Manitoba around the Lake of the Woods on the border with Ontario and Minnesota, east to Newfoundland, south to Florida, and southwest to eastern Texas. At maturity, it often attains a height of around 30 m (100 ft). It might be too much direct sunlight (the tree likes shade), or it might be too much wind. Flowers well before leafing out. In one study, stem elongation was one-half completed in 1 week, after which growth slowed and was 90% completed within only 54 days. The petriole on a red maple leaf is also distinguishable by its longer length, often growing as long as 2 inches. Elk and white-tailed deer in particular use the current season's growth of red maple as an important source of winter food. Side buds much smaller than terminal buds and angled in the direction of the twig. As the tree grows the bark becomes darker and cracks into slightly raised long plates. Put your maple in … One study compared the sap and syrup from the sugar maple with those of the red maple, as well as those of the Acer saccharinum (silver maple), Acer negundo (boxelder), and Acer platanoides (Norway maple), and all were found to be equal in sweetness, flavor, and quality. [8] Its ideal conditions are in moderately well-drained, moist sites at low or intermediate elevations. The fruits also vary geographically with northern individuals in areas with brief, frost-free periods producing fruits that are shorter and heavier than their southern counterparts. Soil acidity can influence the color of the foliage and trees with female flowers are more likely to produce orange coloration while male trees produce red. Generally speaking, individuals from the north flush the earliest, have the most reddish fall color, set their buds the earliest and take the least winter injury. They are very tolerant of flooding, with one study showing that 60 days of flooding caused no leaf damage. The Red Maple is botanically called Acer rubrum . [21], Numerous cultivars have been selected, often for intensity of fall color, with 'October Glory' and 'Red Sunset' among the most popular. The Tree is a deciduous tree, it will be up to 20 m (66 ft) high. Symptoms occur within one or two days after ingestion and can include depression, lethargy, increased rate and depth of breathing, increased heart rate, jaundice, dark brown urine, colic, laminitis, coma, and death. Below is a partial list of cultivars:[22][23], In the lumber industry Acer rubrum is considered a "soft maple", a designation it shares, commercially, with silver maple (A. saccharinum). 264 298 22. [16], Red maple's maximum lifespan is 150 years, but most live less than 100 years. Red maple trees are popular but suffer from a number of problems. The road to Pu Ta Leng peak is dyed the yellow of maple leaves. If you have the same scenario going on with your tree, don’t panic, this is a very common fungus disease called tar spot and is often seen on the Norway Maple, Silver Maple and the Freeman’s Maple. 154 103 69. [19] It is more tolerant of pollution and road salt than sugar maples, although the tree's fall foliage is not as vibrant in this environment. How to Mulch With Maple & Oak Leaves. By removing red maple from a young forest recovering from disturbance, the natural cycle of forest regeneration is altered, changing the diversity of the forest for centuries to come. Underside of mature leaves sometimes much lighter in color than top. Some people refer to these leaves as having a "star" form or a maple-like silhouette. Mature trees have woody roots up to 25 m (82 ft) long. Silver maple or Acer saccharinum. From the little 8-foot (2.5 m.) Japanese maple to the towering sugar maple that can reach heights of 100 feet (30.5 m.) or more, the Acer family offers a tree just the right size for every situation.
