Boston Ivy

Parthenocissus tricuspidata (par-then-oh-SIS-us tri-kus-pih-DAH-tah)

Family: Vitaceae Non-native Vine (vertical)

Boston ivy is a deciduous woody vine originating in China and Japan and is in the grape family (Vitaceae). It is unrelated to English ivy ( Hedera helix ). Boston ivy climbs by short tendrils branched with terminal sucker-like adhesive discs. The species epithet is Latin for “having three points.” This climber grows in a variety of soils, including rocky to high organic matter and in all pH soil types. It needs little care, but can be trimmed back regularly to keep it in bounds. Site it in areas where it will have room to expand and grow. This plant grows well in full sun or shade, is tolerant of excessive wind, pollution, and salt. The plant is cold hardy to about 15 degrees F. It should not be grown up wood or shingle walls because the holdfasts are difficult to remove, can creep under shingles and will ruin the paint. Vines can also attach to and damage such objects as gutters, shutters or wiring around homes and buildings. However, if the plant is killed first, by severing the vine from the root, the adhesive pads deteriorate and the plant can be removed without causing damage to the wall. Leaves emerge in late spring and are green all summer. In autumn, they put on a spectacular display of fall color when the leaves turn from green to burgundy. In its juvenile form, the plant lacks tendrils. This plant attracts bees and birds. Boston ivy can be grown in naturalized areas, in play areas, on rock walls or on other desired vertical structures. Do not allow this plant to grow up trees, as it can overgrow and outcompete many trees. Boston ivy is one of the climbers used to cover the outfield walls of Wrigley Field in Chicago. Diseases, Insects, and Other Plant Problems: No serious insect or disease problems. Mildews, leaf spots, canker and wilt may occur. Potential insect pests include scale and leaf hoppers and Japanese beetles.
