Description

Hedera helix, or English ivy, is an invasive, weedy and aggressive plant and you should consider using other groundcovers that do well in the partial or light shade instead of Hedera helix. English Ivy is a high-climbing evergreen vine that is nearly impossible to eradicate once established and is one of the worst invasive weed problems in North Carolina. It aggressively spreads into native forests, where it smothers tall trees as well as the forest floor, preventing native wildflowers, shrubs, and trees from sprouting. Note that the 80 foot height potential for this plant listed below reflects an outside plant. It is safer, and more common, to grow it as a houseplant. 

When grown outside, the plant prefers partial to full shade and rich, acidic, loamy soil. However, it will tolerate a range of soil conditions and will grow in full sun, although full sun may burn the leaves in the winter. Established vines are hardy and drought and salt tolerant. This plant is frequently damaged by deer.

Cuttings taken from the adult part of the plant develop into a shrub form and, taking into consideration its invasive nature, the plant can be used as an exterior ground cover, or in planters or low walls, stream banks and difficult areas. The plant grows in two stages. The juvenile stage is the climbing/spreading stage producing thick green leaves on non-flowering stems with adventitious roots. The adult stage is the shrubby non-climbing stage in which stems do not spread or climb, but do produce clusters of greenish-white flowers in early fall followed by blue-black berries. The fruits are ornamental, appearing as a bunch of "grapes", but poisonous when ingested.

Exterior plants typically belong to var. Hibernica which is used as an interior plant in hanging baskets, tall planters, or as grafted standards on X Fatshedera lizei stock. These cultivars are commonly from a different variety, not as cold hardy, with smaller leaves. Smaller-leaved cultivars are often used for topiary shapes, houseplants or small area ground covers.

In North America, English ivy frequently occurs in upland and riparian deciduous forest communities of variable species assemblages. It occasionally occurs in conifer forests or savannas in conifer-deciduous mixed forests and in thickets and shrublands . In North America, English ivy is widespread in urban and disturbed forests and is commonly associated with other nonnative species. Forests containing English ivy may have a diverse assemblage of plant species but may become less diverse as English ivy spreads

Diseases, Insects, and Other Plant Problems:

As mentioned, the plant is invasive and the rapid growth of the climbing vines can cause structural problems. The plant is subject to aphids, mealybugs, caterpillars, mites, loopers and scale. Watch for leaf spots, canker, bacterial leaf spot, stem rot and powdery mildew. Climbing vines around homes easily crawl into unintended areas, curl around gutters and damage painted surfaces, loose mortar or aluminum siding if growth is not closely monitored.
