Hedera helix Hedera helix L.
English Ivy
English ivy is native to most of Europe. Introduced to North America and Australia, it is now considered an invasive in some areas. Identification: English ivy is a climbing vine that reaches 66-98' (20-30 m) in height, clinging to rocks, trees and buildings with sticky aerial rootlets, and spreading to cover the substrate almost completely. Vines in well-established plants can reach up to 12" (30 cm) in diameter. Younger leaves have five (rarely three) pointed lobes; in older leaves, the lobes become less divided. Leaves are dark green and waxy or shiny, with prominent, light-colored veins, 1½-4" (3.8-10 cm) long. It takes many years for a vine to begin flowering, and the flowers are inconspicuous, small and greenish. Berries are purple or black, about ¼" (6.3 mm) in diameter, and also rare. English ivy is considered an invasive in some areas because it climbs over and kills many other plants, establishing a less healthy monoculture in place of a more diverse plant community.
