Invasive Description

Introduced from Europe in colonial times, English Ivy is a vigorous evergreen vine or groundcover, growing to 90 feet. Thick, dark-green leaves have whitish veins and 3 to 5 pointed lobes. Terminal flower clusters that yield purplish berries produced after ten years. The berries are toxic to humans.

Ecological Threat

English Ivy is a vigorous-growing vine and groundcover that impacts all levels of disturbed and undisturbed forested areas.  As the ivy climbs in search of increased light, it engulfs and kills branches by blocking light from reaching the host tree’s leaves. Branch dieback proceeds from the lower to upper branches, often leaving the tree with just a topknot of branches. This weakens the tree and with the weight of the vine, makes the tree susceptible to being blown over in windy weather. On the ground, English ivy forms dense and extensive monocultures that exclude native plants. English Ivy also serves as a reservoir for Bacterial Leaf Scorch (Xylella fastidiosa), a plant pathogen that is harmful to elms, oaks, maples and other native plants.
