Emerald Sunshine

Ulmus propinqua (ULM-us da-vi-dee-AY-nah ja-PO-ni-ka)

Family: Ulmaceae Unknown Canopy (>40 ft)

Emerald Sunshine® elm is a woody, deciduous tree in the elm family (Ulmaceae). It is a cultivar bred to be resistant to insects, diseases, heat, drought and wind. It is resistant to elm leaf beetle, Japanese beetle and Dutch elm disease. This tree is not picky about soil type or pH, but prefers moist soil. It requires full sun or partial shade. Give it room to grow as it matures to a height of 30 to 40 feet and a width of 25 to 30 feet. Once established, it is drought tolerant. Emerald Sunshine elm has strong wood, an erect, vase-shaped form, and leaves that start out coppery bronze but mature to glossy deep green. It attracts small mammals and songbirds. Emerald Sunshine elm is an ideal shade, specimen or street tree for coastal areas, drought tolerant gardens, recreational play areas, or lawns when given the space it needs to grow, 24 to 60 feet. Insects, Diseases, and Other Plant Problems: Aphids, borers, beetles, and scale. Disease problems included Armillaria, Phytophthora, root rot, sooty mold and verticillium. VIDEO Created by Elizabeth Meyer for "Trees, Shrubs and Conifers," a plant identification course developed in partnership with Longwood Gardens. More information on Ulmus .
