English Ivy

English ivy (Hedera helix) is an easy-to-grow climbing vine and groundcover popularized by home gardeners for use in residential landscapes. However, this non-native invasive plant can escape from our yards and become a pest in forested settings where its weighty vines can damage and even kill trees. On the ground in natural areas, English ivy can crowd out important native plants by forming dense monocultures, eliminating habitat and food sources for wildlife. Learn to spot this invader, remove it when possible, and replace it with a desirable native alternerative.

Identification

English ivy is a climbing, perennial vine that can also be a low-growing ground cover. It has alternate, dark green leaves with distinct white veins. The waxy leaves are usually three-lobed and have a heart- shaped base. English ivy’s long woody stems can climb trees and are supported by aerial roots.

Ecological Threat

Garden Invaders: English Ivy – Credit: Ontario Invasive Plant Council

English ivy occurs in many types of habitats including roadsides, fields, forest edges and woodlands. It also climbs up buildings and can damage façades. English ivy growing densely on the forest floor can exclude native plants. Climbing trees as high as 300 ft, it can also damage or kill weakened trees which become susceptible to wind or ice storms. Other invasive species can then invade forests with fallen trees where openings in the canopy exist.

Plant Native Alternatives

Landscaping with native plants avoids the threat of invasive ornamentals escaping from your yard to natural settings and has many benefits. Native plants provide beauty, conserve water, and provide habitat and food for wildlife. Below is a sampling of native species to consider incorporating into your home landscape as an alternative to planting English ivy.

Recommended Native Alternatives: Plantain-leaved sedge, Marginal woodfern, Alumroot

*This list is not comprehensive, but rather provides a sampling of species available for purchase from retailers located in Pennsylvania and/or surrounding states. All native plant distribution maps (below) are provided by the Biota of North America Program.

Plantain-leaved Sedge (Carex plantaginea)

Plantain-leaved sedge requires a shady location to grow in along with moist, rich soils.

Marginal woodfern (Dryopteris marginalis)

Marginal woodfern is easily grown in average, medium, well-drained soil in part shade to full shade. It prefers moist, rich, humusy, acidic soils with protection from wind.

Alumroot (Heuchera villosa)

Alumroot is best grown in organically rich, humusy, medium moisture, well-drained soils in full sun to part shade.
