Japanese Ivy Parthenocissus tricuspidata

Parthenocissus tricuspidata, or Boston Ivy, is a deciduous vine typically grown as a ground cover that climbs by short tendrils branched with terminal sucker-like holdfasts or adhesive discs. If vertical support is lacking, the plant will spread across the ground. Leaves emerge in late spring and provide good fall color when the leaves turn from green to burgundy. In its juvenile form, the 3-foliate leaflets resemble poison ivy and lack tendrils.This plant is soil tolerant, grows well in full sun or shade, is tolerant of excessive wind, pollution, and salt. This plant attracts bees.

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. 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 home 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. Boston Ivy, along with Japanese Bittersweet, is used to cover the outfield walls of Wrigley Field in Chicago.

The plant is cold hardy to about 15 degrees F.
