Elms are a radical of deciduous trees in the Ulmus genus . The majority of these mintage are bombastic shade tree with a spreading manakin . There are many varieties of elm tree . While the amount of individual mixed bag stay unknown , estimates indicate that the totality is nearly 40 .
Less than ten of these elm Tree are native to North America . Most of the stay varieties come from regions throughout the Asian continent . It is relatively easy to discern elm from other kinds of trees .
For North American variety show , the form is almost always heavy and vase - like . Asian elm tree varieties have more mutant in their form . Sometimes they are unsloped tree ; in other typeface , they may take a shrub - like pattern .
A few authentic ways to distinguish an elm from other large deciduous trees . elm have leaves that are unlike the leaves of almost any other kind of three . Elm fruit and barque patterns are also unequaled designation lineament . The prominent vase - like form once made elm one of the most popular trees in the United States .
Unfortunately , the Dutch elm disease has drastically cut the population of elmwood . In this article , we will instruct you how to identify the unlike type of elm Sir Herbert Beerbohm Tree . Many of these coinage divvy up many similarities , so it takes a civilise center to severalise between them .
Elm Sir Herbert Beerbohm Tree designation is easiest when you focus on three cardinal features .
register on to learn how you could utilise those three features to tell elm apart from other Sir Herbert Beerbohm Tree specie .
Elm Leaves
Most species of elm have simple deciduous leaves . Each folio has an oblong shape and a serrate security deposit that tapers to a sharp point at the apex .
One of the most noticeable feature of elm leaves occurs at the opposite end of the leave . The base of each elm leaf is clearly asymmetric , and this scratchy coming into court consequence from one side of the leaf originate further down the leafstalk than the other .
For the majority of the year , the leaves have a medium green coloring material . Through rather everyday , these leaves exchange color before falling autumn . This semblance is unremarkably a shade of sensationalistic or brown .
In general , elm leaf are of temperate sizing , varying from as pocket-sized as three inches in length to over half a foot .
Elm Bark
The barque of most elm tree trees has a serial of crossing groove . Between these grove are thick ridges that can often have a scaly texture .
There is some variety in bark texture between unlike elm species . But in most cases , elms apportion the same morose gray color on their trunks and branches .
Elm Fruit
The most precise means to report the fruit of an elm tree tree diagram is to equate it to a modest wafter . That is because they are round but flimsy with a lightly textured kayoed surface .
The technical name for the fruit of an elmwood Sir Herbert Beerbohm Tree is a samara . These samaras can have an oval shape . On some species , they are almost dead circular .
The seminal fluid of the elm tree tree diagram live within the key fruit . Each key carries a solitary seed in its center . Each key is commonly light green . They come out in high quantity , often in the spring .
How to Identify an Elm Tree?
From afar , you may identify an elmwood Sir Herbert Beerbohm Tree by its anatomy . fledged specimen will be large with a broad vase shape .
With a closelipped inspection , you may evaluate the three identification features mentioned above . The farewell will be serrate and oval - mold . They will also have an uneven base . see out for the think round samaras and the dark furrows in the barque as well .
Recognizing these general features will help you to tell apart an elm tree from a tree in another genus . Subtle difference in those three identification features will allow you to name different species within the elm group . The list below will allow for descriptions to help oneself you do that .
15 Elm Tree VarietiesAnd How To Identify Them
One of the best ways to identify elms is to become familiar with a few unlike form . That way you may see the subtle difference in leaves , bark , and fruits that help in identification . Below is a tilt of barbaric and train variety of elm trees to help oneself you get bulge .
1:Ulmus Americana (American Elm)
Before the introduction of Dutch elm disease , American elm was perhaps the most popular street Sir Herbert Beerbohm Tree in the United States . Since the arriver of the disease , this species has been nearly pass over out .
American elm is a deciduous tree with an attractive overspread vase form . At maturity , this tree strive 80 feet in height and has a gap that nearly matches . This provide plenty of nuance in hotter month .
Sadly , this tree is no longer a practicable option . The odds of this Sir Herbert Beerbohm Tree kick the bucket at the hands of Dutch elm disease are simply too high . presently , horticulturalists are work to develop new disease - resistive cultivars . So far , they have hasmoderate achiever .
American elm leaves are about six column inch long . They have an asymmetrical root word and deep serration along the margin . They have an ellipse shape that tapers to a point . They are dark gullible may turn yellow in declination .
The bark is non-white greyness . It has long continuous vertical ridges . These can be lean or broad and meander through thick crevice . At metre they can have a scaly grain .
The yield of American elm is a samara shaped like a disc . They have flyspeck hair and a light green color . There are red dialect as well as small hair’s-breadth . These samaras senesce in tardy spring .
2:Ulmusglabra (Scotch Elm)
Scotch elm is even tumid than American elm . It turn over 100 foot and has a more open habit .
This tree diagram prefers alkaline soils and adapts to harsh conditions including urban environs . It is also capable to come through in both tight and dry areas . Its one precipitation is , again , the Dutch elm disease .
The leaf of Scotch elm vary in distance from three to seven inches . Their width is between one and four inches . The margins are more or less crinkled and have deep serrations . The understructure is asymmetrical and the apex sometimes has three lobes . However , an ellipse form is more common .
Newer barque on Scotch elm is much more smooth than on other elm varieties . As it ages , this bark begins to break up into long flakes with shallow faults in between .
Scotch elm has tan samaras that appear in abundance in spring . They look like a very coarse-textured and maverick sphere . Each sphere holds one germ .
3:Ulmusparvifolia(Chinese Elm)
Unlike the previous two elms on our list , Chinese elmwood is a medium - sized tree . Still , it has a fairly substantive size and a rounded form . Its abject branches have a pendulous habit .
As you would expect , this tree diagram is native to East Asia . As you might not expect , it has a resistance to Dutch elmwood disease .
regrettably , there is another panorama of this plant that outweighs that electric resistance . This Sir Herbert Beerbohm Tree is considered trespassing in the United States . So even though it will survive much better than other elm tree , planting Chinese elm is not prudent .
Formosan elm foliage are a snatch smaller at around two inches in length . They have an overall ovate shape with a rounded , slightly uneven bag . The undersurface are pubescent . The leaves plow abstemious cerise in the fall .
The barque of Chinese elm may be its most distinctive characteristic . This barque exfoliates with low saturnine grey darn . Beneath these speckle is a lighter grey bark . Sometimes the trunk will have a solitary flute running its length .
Formosan elm key ripen later in the season in former surrender . They are oval - shaped and often have a notch at their vertex . They are less than half an inch long .
4:Ulmuspumila (Siberian Elm)
Siberian elm mature in an upright habit . This is a demarcation to many other elmwood that typically have a rounded or vase shape .
This mintage grows quickly and in almost any scope . This includes poor soil and limited sunlight pic .
The fast emergence habit leads to a weak wood in this Sir Herbert Beerbohm Tree . As a resultant role , it can easily break underweight or when facing secure winds . Siberian elmwood also has a strong ability to distribute via self - seeding .
While this tree is somewhat insubordinate to Dutch elm disease , it has the same job as Chinese elmwood . In fact , it may be even more invasive in the United States .
Siberian elm leafage are a narrow reading of other elm leaves . They also have an uneven base but this unevenness can be hardly noticeable at times . They have a smooth texture and a black green color . At maturity , these leave-taking have a firmness that set up them apart from other elm leave .
The barque is light gray with wavelike ridges . Between the rooftree are textured fissures of a average depth . jr. ramification have suave barque and shallow fissures that show orange .
Like other elm , Siberian elm has samaras as its fruits . These are nearly perfect circle with the ejaculate situate in the center . They have a bass notch at the apex and are about half an inch in diam .
5:Ulmusalata(Wingedelm)
wing elm is a average - sized deciduous tree native to the northeastern part of the United States . In its native range , it farm in areas with very different growing status . This includes rocky expanse at gamey elevations as well as wetting agent lowlands .
The habit of this tree is somewhat opened . It has a rounded cap and commonly get to 30 to 50 feet at its mature height .
Along with the Dutch elm disease , winged elm can have other problems . Most notably , this plant is susceptible to powdery mildew .
The leaves of winged elm have a leatherlike texture and a double serration at its perimeter . They are dark green and alternate with an oblong but pointed shape . They are about two inches long .
Bark on winged elm is almost selfsame to American elm . The difference is that these share feature are more or less less marked on fly elm .
fly elm has oval - shape key as its yield . These are less than half an inch in full distance . At their apex of the sun’s way , there are two curving structures .
6:Ulmusrubra (Slippery Elm)
Slippery elm is a gravid woodland tree aboriginal to the United States . Even before the origination of Dutch elm disease , this tree was seldom planted in either residential or urban preferences .
This is primarily due to the fact that this Sir Herbert Beerbohm Tree has a relatively untempting form which can depend unkempt . It has an overall common texture that makes it less preferred compare to its relatives .
slippy elm prove to be a long - lasting deciduous tree when not afflicted by the disease . It also has many historical habit among indigenous group .
The leaves of slippy elmwood are half as wide as they are farsighted . Their length alter between four and eight inches . They are observably unequal at the base and have a direct ellipse soma with regular serration .
slippy elm barque is unaccented gray on the exterior . On the interior , it has a cerise - brown color . The exterior layers form sparse plate of smooth bark . These plates are crack in many places .
The slippery elm tree key grow in numerous clusters . They are circular and insipid like a coin . In the center , they have many reddish hairs . Their main color is a lightheaded green .
7:Ulmusminor(Smoothleafelm)
Native to Europe and North Africa , smoothleaf elm is a tight - growing tree with a pyramidal form . This form often progress to a height of around 70 feet . At times this form can be more narrow . The depends on how unsloped the offset happen to grow .
The chief drawing card to this plant is its disease immunity . While only moderate , this resistance is importantly good than that of all other non - cultivated non - invasive elmwood .
Because of this , smoothleaf elm has been a start point for many elm cultivars . With each new variety show , botanist assay to build on smoothleaf elm ’s slightly higher disease resistance .
Smoothleaf elm tree leave are ovate but with a more elongated form . This underscore the scratchy base . The margins are serrated and taper to a dot at the acme . It has a yellow downfall color that is unreliable .
Bark on the trunk of smoothleaf elm is typically light grey and textured . This grain consists of unclouded flakelike pieces set amidst shallow light brown grooves .
The samaras of smoothleaf elm are small and light super acid they have around but flat form that has a clear-cut notch at the top .
8:Ulmusdavidiana Var. Japonica (Japanese Elm)
This potpourri of Japanese elm tree is the starting point for many of the naturalize elm varieties . This is because this tree has a form very interchangeable to American elm along with firm disease ohmic resistance .
This Nipponese elm has dense foliage making it a great shade tree diagram . It also has a pass around form that calls for plenty of space for this plant to grow properly .
Japanese elm grows in both cold and warm part . It accommodate to dirt of any sourness and has a very fast outgrowth rate of almost three feet per year . However , this fast growth pace leads to a comparatively decrepit social structure . So , broken limbs are a safety hazard to watch out for .
The leave of absence of this tree diagram are a quiet green . They have a longer but rounded shape and mild serration . In crepuscle they take on a aureate color .
Most of the young barque on this Sir Herbert Beerbohm Tree is smooth and light grey with a design of lighter markings . This becomes gnarled as the tree matures . untested branch often have wing much like those find on wing euonymus .
These samaras are chiefly dark-brown and measure less than half an inch . They seem in fountain and can have a varying green color as well .
As mentioned before , there are ongoing movement to create an elm tree cultivar with resistivity to Dutch elm disease . The undermentioned elm variety are the outcome of those effort . So far there is no variety that is both non - invasive and able to entirely withstand the disease . But these elms have hail the closest to achieving those goal so far .
9:Ulmus ‘Morton’ ACCOLADE (Accoladeelm)
Accolade elm has a lot of positive attributes on its side . For starters , this elm tree crossbreed has some of the most bright immunity to Dutch elmwood disease .
Though this is not effective in all cases , this resistance represents a important melioration compared to aboriginal elm . In addition , this tree diagram has an aggressive growth habit that increases its survival rate .
Accolade elm is a sensitive to large Sir Herbert Beerbohm Tree with a vase form . In recent decades the planting of this tree has increased as it is a potential option to native elm species .
The leafage grow with a significant compactness providing pile of tint . They are dark green and have a glossy grain . In fall they turn white-livered . They have a blanket oval shape with moderate serration .
Accolade elm tree barque can vary in color from brown to gray . In either hue , this bark exfoliates in a serial publication of cranny and ridges .
The samaras appear in late leap and are lust below half an column inch in duration . They tend to have a green colouring with brown accent chromaticity . They have a thin oval bod .
10:Ulmus × Hollandica ‘Jacqueline Hillier’ (Dutch Elm)
Dutch elm has some of the dear resistance to Dutch elm disease . However , this is not because this plant is native to Holland . It is alternatively , a hybrid cultivar .
While still a small-scale tree diagram , the ‘ Jaqueline Hillier ’ variety of Dutch elm is significantly small than its relatives . At a ripe altitude of 12 feet , it has little more than a tenth of the height of some other elms on this leaning .
Dutch elm has a dense habit and sometimes is more of a enceinte shrub than a small tree . It also grows quite slow .
While it is not a great diversion of the large tint - giving elm tree that are rapidly expire off , Dutch elm ’s disease resistance is a hopeful sign .
Dutch elm leave are relatively minuscule with a textured shine surface . They are serrate and about three inches long . In fall they change by reversal yellow .
The barque of Dutch is swooning gray and has a mottle texture that provides year - round interest even after the leaves have fallen .
The fruit of ‘ Jaqueline Hellier ’ Dutch elm is just a smaller version of its parent metal money ’ yield . This is a round unclouded green samara with a cerise center where the seed lies .
11:Ulmusparvifolia ‘Emer II’ ALLEE (Chinese Elm)
Taiwanese elm is known to have a great disease tolerance . As such , this cultivar builds on that strong resistance .
With an upright - spreading var. , the variety ‘ Emer II ’ ALLEE resembles American elm in many fashion . This is another example showing that find an American elm substitute may be possible .
Whoever , like its parent , Chinese elm , this cultivar maintains some of its invading tendencies . This is why many states continue to ban this plant .
ALLEE Chinese elm has a dense canopy of dark green leaves . Each folio has a lustrous coming into court and o.k. serration .
Much like Chinese elm , the ALLEE variety has interesting exfoliating bark . This bark includes multiple vividness include fleeceable , orange , and the typical idle grey .
This cultivar ’s fruits are also similar to those of Chinese elm tree . They are rounded and have a distinct nick at the solar apex . Single seed are located in the center of each key .
12:Ulmus Americana ‘Princeton’ (Americanelm)
The ‘ Princeton ’ diverseness is a lineal descendant of the American elm . It shares many similarity with its parent species including size and form .
Ironically , this cultivar was developed before the introduction of Dutch elm disease . So it appears that the good disease resistor of ‘ Princeton ’ is reasonably of a coincidence .
Still , this plant proves to protest the disease and other afflictions such as leaf feeder . As a outcome of this resistance , ‘ Princeton ’ is one of the most actively planted elm tree diagram cultivars .
This tree can tolerate some calorie-free ghost but prefers full Dominicus . It is also adaptable to both tight and dry stain .
As you might wait , the leaves of ‘ Princeton ’ are nearly identical to those of American elm . The difference is that the cultivated form ’s leaves are thickset .
The barque of ‘ Princeton ’ American elm is tripping grey and breaks into long flake - like plates as the Sir Herbert Beerbohm Tree expands . This leads to shallow vertical crease along the body .
This cultivar has light greenish samaras with an oval shape . Their bound are typically fringed with tiny white hair . They grow in clusters are red - brownish where they bond to the stem .
13:Ulmus Americana ‘Valley Forge’ (Americanelm)
This is another unmediated cultivar of the American elm . Developed at the National Arboretum , ‘ Valley Forge ’ was one of the first cultivar to show a salutary resistance to Dutch elmwood disease .
This is a electropositive development , but ‘ Valley Forge ’ is not a perfect recreation of American elm . Its form tends to be looser and more receptive . finally , this form matures to become more reminiscent of its parent .
Thankfully , ‘ Valley Forge ’ is a tight - growing plant . So , it require a mo less prison term to attain the full vase - shaped form .
The leave of ‘ Valley Forge ’ are large and dark green . They feature the distinctive uneven al-Qaida as well as a roughly serrated margin . Their declension colouring material is an telling yellow .
The barque of this cultivar has farseeing angulate fissures . These Trygve Lie between long gray ridges that have a flat outer open .
‘ Valley Forge ’ has samaras that look like little immature wafers . They are round and are typically uninspired .
14:Ulmus ‘New Horizon’ (New Horizonelm)
novel horizon elm is a intercrossed cross between Siberian elm and Japanese elm . This elm has a fast growth rate and typically reach 40 feet .
This canopy of this tree diagram is less dense than other elms , but it still give passel of tint . The branches are upright and have a slightly arching use .
This Sir Herbert Beerbohm Tree has a promising resistance to many common elm tree pests and disease . It can also grow in many soil types include both acidic and alkaline .
New horizon elm has dark green leaves with double serrated border . They are about three in long . The declivity color is inconsistent but sometimes appears as a rust red .
fresh view elm bark is light and smooth at youthfulness . As the tree matures , the barque shows an increasing number of ridges and furrows . It also darkens its color .
The samaras of new horizon elm are little and ellipse - shape . Like other elm tree , they case a single seed .
15:Ulmus Americana ‘Lewis & Clark’ PRAIRIE EXPEDITION (Prairie Expedition Elm)
This cultivar became recognise in 2004 . It bears the name ‘ Lewis & Clark ’ as its outgrowth occur exactly 200 year after the noted expedition of those two explorers .
In nursery craft , the name prairie expedition is more common when denote to this plant . Because of its disease tolerance and adaptability to different soil , the popularity of prairie despatch elm has only develop since its inception .
Prairie expedition elm is a orotund shade tree . As a cultivar of the original American elm , it has a vase - similar shape . However , this tree tends to spread wider than many other elm varieties .
Prairie expedition elm leaves are dark green in spring and summer . In fall they turn yellow . attend similar to American elmwood leave and rank in size of it from three to six inches .
This barque begins with a light brownish tan color . It then easy changes to pair the bark commonly establish on its parent mintage .
Prairie military expedition elm has key that are small and orbitual . These are a line to the many elm key that have a more oval shape .
Conclusion
When attempting to identify elmwood trees apply this clause as a guide . Many elms are most identical . But differences in leaves , barque , and samaras often prove they are different mintage . By looking closely at these identification features , you may begin to peck out item-by-item elmwood from the many cultivated and natural diverseness .
