After ivy, this three-lobed wild vine is the "dearest child" in facade greening. The Boston Ivy Vine (also known as Japanese Creeper) is a self-clinging climber that covers extensive areas quickly. Its striking red autumn colouring and the fact that it does not require growth supports make it a popular climber. It can be used to fully cover walls on facades, masts, and poles; with regular pruning it can also be used for partial greening and on small, limited wall surfaces. In short: an excellent facade plant!

These vines need a sunny (full sun) to (semi-)shaded location, as they will develop more beautiful autumn colours in the sun. Distance between two plants: 2.5 - 5 metres.
This is a climbing vine with adhesive pads that cling onto nearly every surface. The growth is broad and fan-shaped; the shoots will grow horizontally as well as vertically. This ivy can reach a height of 20 metres and more, with a yearly growth of 1 - 2 metres. The shoots may hang over/cascade. Foliage is from May to October; has inconspicuous, tiny green-yellow flowers in early summer and small black berries which will feed bees and birds. Summer prune as needed to restrain the vigorous growth habit; winter prune as illustrated and described in photos.
The Boston Ivy, unlike other "wild vines," usually has no need for a climbing support. However, in some cases and especially on wind-exposed walls, rope systems (see below) in the easy or medium range which prevent collapsing, may be required. In cases of very tall walls, heavy or even massive wire rope systems may be required. In very old specimens, the main framework may need to be attached as per rope system 1010.
Boston Ivy can cause significant damage to buildings! The plant grows in a light-shunning way and, as the shoots get into nooks and crannies and increase their stem girth, they can blast apart building elements, block roller-shutter boxes, and lift roof shingles! Insufficient removal of foliage may also block roof gutters. A frequently asked question during the restoration of a façade is how to deal with the remaining adhesive roots of torn-off vines. The only solution is to burn them off / torch them and then repaint the wall!
