CENTRAL JERSEY INVASIVE SPECIES STRIKE TEAM Invasive Plant Fact Sheet Five-leaf Aralia (Eleutherococcus sieboldianus) Also called: Acanthopanax sieboldianus ‘variegatus’ Family: Aralia (Araliaceae) Native range: Eurasia General: Fast growing deciduous shrub 6 to 8 feet tall and 6 to 8 feet wide. Branches arcing with short spines at each leaf bud along the stems Leaves: Alternate, toothed, palmately compound leaves with 5 to 7 leaflets; 1 to 2.5 inches long, bright green. Variegated forms have leaves edged in white. Turning yellow in autumn. Flowers: Small, greenish white borne in clusters. Appearing May through June. Fruit: Small, black borne in clusters. Look-alikes: Goutweed also called Bishop's weed (Aegopodium podagraria) is a highly invasive, non-native groundcover or creeping plant with 9 leaflets on lower leaves. Upper leaves may be variable. Some varieties of this plant may have white edges. Goutweed is widely planted in landscaping. It is highly threatening to natural plant communities. All detected occurrences should be eradicated. Habitat: Forest, open forest, forest edge, hedgerow, garden. Highly tolerant of a wide range of conditions. Threats to native habitats: Five-leaf aralia can form thickets that displace native plants and prevent growth of native trees, shrubs, and herbs. NJ Status: Five-leaf aralia is uncommon. It is highly threatening to natural plant communities. All detected occurrences should be eradicated. Commercial Availability: Five-leaf aralia is widely planted for landscaping.
