Your Botanical Expert Dr. Hailey Returns

Welcome back, As your resident plant expert, I’m excited to share my knowledge about another iconic species, the American elm. For centuries, elms lined streets and graced parks across North America. 

Their natural elegance and environmental benefits made them fundamental parts of communities. Through first hand observations and research, I’ve gained deep respect for these beautiful trees. Let me tell you more about the American elm.


The Majesty of American Elm Trees

The American elm was once considered a quintessential tree of the Eastern United States. It rapidly grew along waterways and thrived in many regions. Settlers documented vast forests and individual specimens stretching over 100 feet tall.

American elms were integral to ecosystems and provided shelter, nesting areas, and food for wildlife. However, in the mid 20th century, Dutch Elm Disease arrived via imported elm bark. It devastated native elm populations across North America. Over one billion elms are estimated to have been lost. While breeding programs work to develop resistant cultivars, the iconic tree nearly vanished from the landscape.


American elms can reach heights over 100 feet with broad, arching branches forming a vase shape. The bark is gray and furrowed vertically with age. Leaves are alternate, simple, and doubly serrated along rich green blades up to 7 inches long. 

In spring, tiny reddish flowers appear before leaves. Samaras or ‘helicopter seeds’ twirl from late spring to fall, easily dispersed by wind. Roots spread widely and rootsuckers allow elm colonies to spread vegetatively. It is hardy from USDA zones 3-9.

Fall Foliage

In autumn, the elm’s leaves take on beautiful shades of yellow, gold and reddish orange hues. However, this only lasts briefly before leaves drop, sometimes as early as late September in colder regions. The flushed colors are most vibrant in full sun positions. 

Individual trees may vary more than other species as fall conditions like temperatures influence how rapidly pigments change. Despite its short duration, the American elm’s fiery foliage is a highlight of many Northeastern landscapes each October.

Table of Selected Cultivars

CultivarDescriptionDisease Resistance
‘Jefferson’Upright, vase shape reaching 80′. Fast growth. Tolerates wet soils.Resistant to DED Race 1.
‘New Harmony’Columnar form, narrow crown. Tolerates urban conditions and soil compaction. Showy red samaras.Moderately resistant to DED Race 1.
‘Princeton’Broad pyramidal shape. Drought tolerant once established. Tolerates clay soils. Autumn colors.Highly resistant to DED Races 1 & 2.

Uses in Landscapes

The American elm has many uses as an ornamental and shade tree choice. Its vase shape is well suited for large lawns, parking lots, and paved spaces needing overhead canopy. It tolerates both wet and dry soils, making it versatile for rain gardens, bioswales, and other stormwater facilities. Elms provide dappled shade beneath spreading branches. 

Their roots are not too invasive for planting near structures given deep, infrequent watering. Colonies along streams and fields impart natural beauty. Elms once lined countless streets and neighborhood   cultivars now help restore this architectural quality.

Wildlife Value

American elms support biodiversity, notably for birds. Cavities from woodpeckers create homes for chickadees, wrens, owls and other cavity nesting species. Larval host plants include the extremely rare and federally endangered Arogos skipper butterfly. Samaras are a primary food source for squirrels, chipmunks, and turkeys in fall. 

Various moths, beetles and other insects use elms for food and habitat, in turn providing for birds and other predators. Elms stabilize stream banks and provide windbreaks, moderating microclimates. Their wide canopy shelters breeding pools for amphibians like wood frogs.

Sustainable Management

Homeowners and land managers can aid the recovery of elms. When possible, select resistant cultivars for new plantings to recreate lost habitats. Monitor trees for stress factors like drought or construction damage making elms more vulnerable to disease. Water deeply during dry spells and avoid unnecessary pruning which invites infection. 

Mulch gently slopes to retain moisture while not compacting soil. Management also involves removing dead wood promptly to inhibit fungal spread from diseased fall debris. With proactive stewardship, a diversity of elms may regain presence in suitable growth zones.

Traditional Medicinal Uses

Various indigenous tribes across North America utilized American elm medicinally. The inner bark was depicted as a treatment for coughs, colds, wounds and sores when applied topically. As an astringent and antiseptic, it aided healing and relieved pain. Tea from the bark alleviated diarrhea and upset stomach. 

Some tribes chewed fresh inner bark directly as temporary relief from toothaches. Elm sap was rendered into syrup to soothe sore throats. Entire plants possessed antifungal properties applied for skin infections like ringworm. While little modern research validates these traditional uses, elms likely contained antibacterial compounds before being overharvested.

Folklore and Cultural Significance

Many myths and legends surround the elm within Native American spirituality and folk traditions. Tall elms lining ceremonial trails represented a connection to sky spirits watching over communities. Their wide canopy signified shelter and protection. Stories told of elms giving shade, singing in the wind and communicating wisdom between realms. 

Trees lived alongside people as respected elders. Elms appeared in petroglyphs, dances and oral histories. For settlers, elms marked boundaries and landmarks on journeys west. Their longevity stood as a symbol of perseverance   Elm City was emblazoned on items from New Haven, Connecticut. Despite loss, the elm’s deep cultural roots live on through tales nurturing relationships with the natural world.

Concluding Thoughts

While disease challenges remain, breeding programs coupled with sustainable practices offer hope that American elms may once more find an established place within our ecosystems and culture. As keystone species supporting biodiversity, their recovery benefits countless other forms of life. 

Through traditional knowledge and modern research, a holistic understanding of elms continues to unfold   one encompassing both practical and spiritual dimensions. With diligent stewardship, future generations may know elms not just through memory, but directly experience the majestic arching branches providing shelter within our communities.
