Hedera helix, commonly known as English ivy, is an aggressive, vigorous, fast-growing enduring perennial primarily cultivated as a trailing ground cover or climbing plant. As a climbing plant, it can reach heights of 50 to 100 feet over time.
It usually grows 6 to 9″ in height as a trailing ground cover but expands to 50-100 feet over time. Hedera is a genus of 12 to 15 evergreen plants in the Araliaceae family native to southern, central, and western Europe, northwest Africa, Macaronesia, and central and southern Asia.
English ivy typically grows in two stages or forms: (1) The juvenile stage is the spreading/climbing stage when plants produce thick, 3 to 5 lobed deep green leaves (up to 4 inches long) on non-flowering stalks with root hairs, and (2) the adult stage is the non-climbing shrub stage in which elliptical-ovoid, lobed deep green leaves are borne on rootless stalks that do not extend or climb.
On the contrary, they form round – greenish umbrella-like clumps – white flowers in early autumn.
