hiedra

Hiedra, in botany commonly known as common ivy, refers to Hedera helix and other species in the Hedera genus, a group of evergreen climbing plants in the family Araliaceae. Native to Europe and western Asia, hiedra has been widely cultivated and naturalized elsewhere, where it often grows on walls, trees, and as ground cover.

Hedera helix is an evergreen climber or ground cover. It climbs by means of aerial roots that attach to walls, trees, or other structures, enabling it to reach and cover large areas. Juvenile leaves are usually lobed (typically 3–5 lobes) and dark green; flowering shoots bear larger leaves that are less lobed or unlobed.

Native range includes Europe and western Asia; it has been introduced worldwide and is naturalized in many temperate regions. It commonly grows in shade, on forest margins, and in urban environments, tolerating a range of soils and conditions.

Beyond ornament, hiedra provides ground cover and shelter for wildlife, but can suppress native vegetation when it becomes invasive. It is widely propagated for cultivation, including cuttings and layering, and is valued for its tolerance of shade, drought resistance, and use on walls, fences, and green façades.

In some regions, especially parts of North America and Oceania, common ivy is considered invasive. It can smother trees and understory plants, alter light regimes, and change habitat structure. Management includes mechanical removal, regular pruning, and, in some cases, herbicides, with careful disposal to prevent spread.

All parts can be mildly toxic if ingested by humans or pets, and handling can occasionally cause contact dermatitis for sensitive individuals. It is not the same plant as poison ivy (Toxicodendron species), a different genus.
