Accolade Elm (Ulmus ‘Morton’) Accolade Elm is a hardy, disease-tolerant shade tree with a graceful, classic elm form featuring an upright vase shape and arching limbs. Glossy dark green foliage casts broad, cooling shade and turns yellow in fall, making a reliable anchor for streetscapes and large landscapes. Distinctive Features Bred for strong resistance to Dutch elm disease with excellent tolerance of urban stresses, wind, and cold. Uniform branching and a high canopy echo the look of American elm while offering modern durability. Growing Conditions Sun Exposure: Full sun for best canopy density and form. Soil: Adaptable to a wide range of well drained soils; prefers slightly acidic to neutral conditions. Water: Moderate; keep evenly moist during establishment, then water deeply in extended dry spells. USDA Hardiness Zones: 4 to 9. Mature Size: Typically 50 to 60 ft tall and 40 to 50 ft wide. Ideal Uses Focal Point: Iconic vase-shaped canopy provides architectural structure and generous shade. Shade Tree: Cools lawns, play areas, and patios with a high, spreading crown. Street Tree: Performs along sidewalks and medians with good urban tolerance. Allees and Drives: Arches elegantly when planted in rows to frame entries. Parks and Campuses: Reliable large-scale shade for open greens and gathering spaces. Low Maintenance Care Watering: Water weekly the first 2 to 3 years; reduce to occasional deep soaks during drought. Pruning: Train early for strong central leadership and good clearance; prune in late winter to remove dead or crossing wood. Fertilizing: Feed in early spring only if soil tests indicate deficiency. Mulching: Maintain a 2 to 3 inch mulch ring to conserve moisture and protect roots, keeping mulch off the trunk. Notes: Monitor for insects typical of elms; overall cultivar shows strong Dutch elm disease resistance. Why Choose Accolade Elm? Disease Resistance: Bred for resilience against Dutch elm disease. Classic Elm Silhouette: Upright vase form with arching branches. Urban Toughness: Handles heat, wind, and city soils better than many shade trees.
