Invasive plant
English ivy
Hedera helix
English ivy identification: lobed juvenile leaves creep and climb, while unlobed adult leaves flower and fruit. The vine stays green all winter.
Published Last reviewed
English ivy is a woody evergreen vine with two leaf forms. Juvenile growth has three- to five-lobed leaves and does the climbing. Adult growth has unlobed, spade-shaped leaves, and only that form flowers and fruits.
That one fact settles most of the confusion. The lobed leaves people recognize belong to a vine that is still spreading. When a stem finds a tree or wall and grows upward for several years, it changes into a shrubby, outward-branching adult stem. The adult form is the one that produces greenish-yellow flower clusters in fall and the blue-black berries that birds spread. So a vine covered in berries is not a young plant that might stay put. It is a mature plant already producing seed.
The two-form check
- Lobed leaf, stem pressed flat against bark or brick, no flowers. This is juvenile growth. It spreads but does not reproduce.
- Unlobed, spade-shaped leaf on a branch standing away from the support, often with flower or berry clusters in fall. This is adult growth. The vine is mature enough to fruit.
- Both forms can sit on the same plant. Look at the stems that reach outward, not only the ones pressed flat.
On a tree, English ivy does more than add weight. The vines hold moisture against the trunk and loosen the bark, which creates conditions for fungal disease and decay, and the added weight makes the tree more vulnerable in wind, snow and ice. A heavily covered tree can eventually die. Cut the stems at ground level and pull the vine free as high as you can reach. On the ground, repeated mowing and digging, or a smothering layer of cardboard or landscape fabric, can clear a patch, but ivy regrows from stem pieces and seed, so plan on returning.
The sap can cause a red, itchy rash and blisters, and the leaves and berries are toxic if eaten, so wear gloves, long sleeves and eye protection when you work on a large patch. For more on the plant side of the site, see the plants hub. For another twining vine that smothers trees, see Oriental bittersweet. The removal guide covers method and timing, and the prevention guide covers what to plant instead. If you are comparing vines, the look-alikes hub is the place to start.

Identification
Look for the combination of characters below. A single feature is rarely enough, especially when a native look-alike is present.
- Juvenile leaves
- Young growth carries the familiar three- to five-lobed, glossy, dark green leaves, 2 to 4 inches long, with pale veins. Leaves alternate along the stem.
- Adult leaves
- Once a stem stops creeping and matures, its leaves lose the lobes and become spade- or diamond-shaped. These stems branch outward and are the only ones that flower.
- Climbing method
- The vine does not wrap or use tendrils. It grips bark, brick, stone and other textured surfaces with dense root-like holdfasts called aerial rootlets.
- Flowers and fruit
- Mature growth produces rounded clusters of small greenish-yellow flowers in fall, followed by clusters of blue-black berries that ripen over winter.
- Growth habit
- Without a support the plant stays under about 1 foot tall and roots at its nodes as it creeps. Given a tree or wall it can climb 60 feet or more.
- Sap and toxicity
- The sap can irritate skin, causing redness, itching and blisters. The leaves and berries are toxic to people, and the foliage is more toxic than the fruit.
Look-alikes

Periwinkle (vinca)
Vinca minor
Periwinkle has opposite, oval, leathery leaves about 1 inch long and blue-lavender flowers in spring. English ivy has alternate, lobed juvenile leaves and climbs with aerial rootlets rather than trailing flat stems.
-
Poison ivy
Toxicodendron radicans
Poison ivy has compound leaves with three leaflets and loses its leaves in winter. English ivy has simple leaves and stays green year-round.
-
Virginia creeper
Parthenocissus quinquefolia
Virginia creeper has palmately compound leaves, usually with five leaflets, and climbs with tendrils tipped by adhesive discs. It is deciduous, while English ivy keeps its leaves all winter.
Range and status
Native range: Europe, western Asia and northern Africa

English ivy is not on the 6 NYCRR Part 575 prohibited or regulated plant list.
-
virginia Not on the state noxious-weed list

-
ohio Not on the state noxious-weed list
English ivy is not on Ohio's invasive plant list (OAC 901:5-30-01) or prohibited noxious weed list (OAC 901:5-37-01).
-
wisconsin Not on the state noxious-weed list
English ivy is not on Wisconsin's NR 40 prohibited or restricted species list.
Why it matters
Dense ivy mats block sunlight and crowd out native wildflowers, tree seedlings and other ground-layer plants. On trees, the vines hold moisture against the bark, loosen it and add weight that snow, ice and wind can turn into breakage. English ivy can also carry bacterial leaf scorch, a disease that affects maples, oaks and elms.
Management
Cut climbing vines at the base
Cut every stem where it leaves the ground, then pull the vine off the trunk as high as you can reach. Growth above the cut dies and eventually falls away. Work carefully so tools do not cut into the bark, because wounded trunks invite decay.
Exhaust groundcover patches
Timing: Repeated through the growing season.
Repeated close mowing, followed by digging out the roots, will weaken a patch. Where digging is impractical, cut the growth back and cover the area with a double layer of landscape fabric, black plastic or cardboard, then add mulch. Check the edges for runners that escape.
Herbicide for large patches
Timing: Spring, when new growth has two to four leaves.
NC State Extension found glyphosate more consistently effective than triclopyr on English ivy, with the best results in spring when the vine has two to four new leaves. WSU lists triclopyr products for turf and bare-ground sites. Follow the product label; the label is the law, and state rules can differ.
Expect a second and third pass
English ivy can regrow from small stem pieces and spreads by seed. Return to the site several times a year and pull new plants before they establish.
