You might be someone looking to landscape your backyard with ornamental shade trees. Elm trees offer the most dramatic canopy throughout the year since they can tolerate the extreme growing conditions.
There are over 35 species of elms where eight types hailing from North America. Other types of elm trees are native to China, India, Central Asia, and Eastern Siberia. The tree barks, leaves, and seeds are features that help tell the difference between elm varieties.
Knowing the different types of elm trees and their characteristics will help choose the best species ideal for landscape design. Below is a breakdown of the most common elm tree types with their growing requirements.
What Is An Elm Tree?
An elm tree is a tall deciduous or semi-deciduous tree that belongs to the genus Ulmus and the family Ulmaceae. The genus Ulmus has over 35 different species ranging from forest trees to ornamental trees.
These trees are native to North America (North Temperate Regions) since they can tolerate extreme growing conditions. Many landscape enthusiasts prefer cultivating these trees due to their height and attractive foliages.
The Elm-wood is suitable for constructing boats, furniture, and farm buildings since they are durable underwater. But the Dutch elm disease has reduced the population of these trees in North America and other European countries. (Source: University of Minnesota).
Some elm varieties are more resistant to the Dutch elm disease than other elm tree types. We recommend you read this article to pick the best American elm tree for your backyard. We also hope the pictures of elm trees will help you make an informed decision.
What Do Elm Tree Look Like?
There are about 35 elm species in the United States, Canada, Asia, and Europe. Each species vary in appearance, size, shape, and leaf type (Source: American Forestry Association). Below is a breakdown of the most common characteristics of elm trees:
Elm Tree Leaves
Elm trees have oval-shaped leaves with serrated edges and pointed tips. The staggered leaves are arranged alternately to create a dense canopy for providing the best shade.
Most elm varieties have light-green to dark-green foliages that turn golden or dull yellow in the fall. The leaf size ranges from 10-12 cm long and 7cm wide.
The visible green veins and jagged leaf blades will make your backyard stand out from the neighborhood. But the leaf veins’ visibility will vary depending on the elm tree species.
Elm Tree Seeds
Elm tree seeds are encased in a samara (seed pods) and produced at the end of the bloom phase. The samaras are oval-shaped and light green with light textured outer surfaces.
Each samara carries solitary seeds at the center and appears in large quantities during spring. These seeds disperse during the late spring and summer when the pods dry out.
Elm Tree Bark
Elm tree bark is dark grayish-brown with deep furrows and a scaly appearance. These deep fissures run vertically and intersect with each other resulting in a lace-like texture.
Some elm types have more colorful barks that are smooth throughout. It helps make it easier to distinguish different types of elm trees.
How to Identify Elm Trees?
Elm trees are identifiable by their dark grayish-brown bark with deep furrows, pointed oval leaves with serrated margins, and large sprawling canopy. (Source: University of Nebraska).
Elm trees also produce flowers during spring that mature into round samaras and seeds. Besides that, the elm leaves turn golden or dull yellow during the fall season.
The alternating leaf growth on each branch is a prominent feature for identifying elm trees. The leaf growth pattern is ideal for creating a dense shade.
Different Types of Elm Trees with Pictures
Slippery Elm (Ulmus rubra)
It is a medium-sized deciduous tree with a vase-shaped to broad and round crown. The elm tree species has red inner-bark and reddish-green flowers. These elm species are native to the central and Southern United States.
The slippery elm tree also derives its name from the sticky red secretion from the inner bark. The elm species are vulnerable to Dutch elm disease and phloem necrosis, making them unsuitable for landscaping.

Are Elm Trees Evergreen?
Elm trees are semi-deciduous since they lose leaves for a shorter period. These trees usually experience leaf color change during the fall before shedding them. Evergreen trees stay green throughout the year. (Source: University of Minnesota).
How Fast Do Elm Trees Grow
The average growth rate of American elm trees ranges from 3 to 6 feet tall per year. The annual growth exceeds the minimum requirement for fast-growing trees. We recommend providing a conducive growing environment for better results.
How Long Do Elm Trees Live?
The average life expectancy of American elm trees is about 300 years. But this life expectancy does not apply to all elm trees due to different species and growth. Different elm species have unique maturity rates, sizes, and care routines.
Do Elm Trees Have Deep Roots?
American elm tree root system varies depending on the soil texture and moisture. Elm trees in heavy and wet soil will develop wide-spreading root systems. On the other hand, those in drier soil will develop a deep taproot system.
Conclusion
Elm trees are vulnerable to the Dutch elm disease. But these trees can tolerate many growing conditions and have a longer life expectancy. Besides that, they provide attractive shade and are dependable for many uses. (Source: Colorado State University).
The high-quality timber and medicinal properties are crucial benefits. Elm trees come in different species distinguishable by the leaves, bark, and seeds. We hope these outstanding credentials will help you differentiate between all types of elm trees.
