Scotch Elm (Ulmus glabra 'Camperdownii') is a distinctive weeping cultivar of the native Eurasian Wych elm, grafted as a top-grafted tree that grows 15 to 25 feet tall and spreads 20 to 30 feet wide. Once a beloved shade tree across American lawns and parks, this deciduous tree produces insignificant reddish-green flowers in spring before its leaves emerge, followed by delicate, wafer-like winged seeds. Hardy in zones 4 through 6, it thrives in full sun with moderate water and moderate maintenance, adapting well to both wet and dry soils while tolerating urban conditions.

Scotch Elm's graceful weeping form sets it apart from upright elm species, creating an elegant silhouette in the landscape. As a top-grafted cultivar, it cannot be grown from seed, making it a nursery specialty that requires deliberate propagation. Its remarkable resilience in urban environments and tolerance of both drought and wet sites gives it surprising versatility for a large tree, though gardeners should understand the serious disease challenges that led to its decline in American horticulture.
Scotch Elm serves as an ornamental shade tree for large landscapes and rain gardens. Its broad, weeping crown once made it a choice specimen for parks and estates where substantial shade coverage was desired. Today it functions primarily as a landscape specimen in regions where disease pressure remains manageable, valued for its architectural form rather than its functional role.

Transplant nursery-grown grafted specimens in spring or fall when soil is workable. Space plants 20 to 30 feet apart to allow full canopy development. Plant at the same depth as the root ball, ensuring the graft union remains above soil level. Water thoroughly after planting to settle soil around the roots.
Prune Scotch Elm in late winter or early spring to shape the weeping form and remove dead or crossing branches. Because 'Camperdownii' is a top-grafted cultivar, maintain its distinctive weeping silhouette by allowing long shoots to drape naturally while removing any upright growth that emerges from the graft union or branches. Minimize pruning beyond structural maintenance, as excessive cutting can invite disease.

“Scotch Elm originates from a wide geographic range stretching from Great Britain across to Siberia, where Ulmus glabra occurs naturally. The 'Camperdownii' cultivar represents a weeping selection that was propagated through top-grafting rather than seed, a deliberate horticultural choice to create a distinctive ornamental form. During the twentieth century, this tree and its relatives were planted extensively throughout the United States as shade trees for large properties and public spaces, becoming a familiar feature of the American landscape before disease epidemics fundamentally altered their use.”
