Winterberry Euonymus

Euonymus maackii (yoo-ON-ih-mus MAK-ee-eye)

Family: Celastraceae Non-native Understory (15-40 ft)

Winterberry Euonymus is a winter hardy semi-evergreen that can be grown as a shrub with significant pruning, or as a small tree. At maturity it can reach a height and width of 25 feet, therefore, the location should accommodate the mature size. In its native Asia, it is often found in shrubby formations in river valleys, coastal plains, and alluvial sands. In cultivation, it is often used as a specimen or a windbreak on hillsides, large native area, or commercial or industrial parks. Fall leaf colors may be muted, depending on location but are often in the yellow brown range. Tree offshoots can invade into undesirable areas, especially if near roadsides or woodlands and the tree is unattended. The tree is semi-evergreen because leaf drop is late and often only a few weeks before spring leaves begin. This is one of the most common species in the genus. Its growth is quite variable under both cultivated and wild conditions. The plant will grow well in most soils with full sun or partial shade, but it does not tolerate wet conditions. Insects, Diseases, and Other Plant Problems: Euonymus scale is a problem with most species of this plant. The Clemson Cooperative Extension Home & Garden Information Center has a factsheet on common pests and diseases. More information on Euonymus .
