Lacebark Elm

Description: Lacebark Elm is a medium to large-sized tree with a rounded or vase-shaped canopy. It features small, dark green leaves that turn golden-yellow in the fall before dropping. One of its most distinguishing features is its bark, which exfoliates in irregular patches to reveal mottled patches of gray, green, orange, and brown, adding visual interest to the tree year-round. Inconspicuous greenish flowers appear in spring before the foliage emerges. The tree produces small, winged fruits called samaras, which mature in late summer or fall.

Size: Lacebark Elm typically grows to a height of 40 to 50 feet (12 to 15 meters) with a spread of 30 to 40 feet (9 to 12 meters). However, under optimal growing conditions, it can reach heights of up to 70 feet (21 meters). The size of the tree can be influenced by factors such as soil quality, moisture, and available sunlight.

Best Growing Zones: Lacebark Elm is well-suited to a wide range of climates and soil conditions. It is most commonly cultivated in USDA hardiness zones 5 to 9. This tree thrives in regions with hot summers and moderate winters but can tolerate cold temperatures and drought once established. It is adaptable to various soil types, including clay, loam, and sandy soils, as long as they are well-drained.

Soil Requirements: Lacebark Elm prefers moist, well-drained soil but can tolerate a range of soil conditions, including clay and compacted soils. It is moderately tolerant of drought once established but benefits from regular watering, especially during periods of prolonged dryness. The tree prefers slightly acidic to neutral soil pH but can tolerate slightly alkaline conditions.

Maintenance: Lacebark Elm is relatively low-maintenance once established. It should be planted in a location with full sun to partial shade exposure. Regular watering is essential, especially during the first few years after planting, to promote establishment and healthy growth. Pruning may be necessary to remove dead, diseased, or crossing branches and to maintain a desirable shape. The exfoliating bark should be left intact, as it adds to the tree's ornamental value.
