Parthenocissus tricuspidata "Veitchii"

The Boston Ivy Vine or Japanese Creeper, a self-clinging climber, covers extensive areas quickly. The fact that it does not require growth supports and its striking red autumn colouring make it such a popular climber. Apart from the English Ivy, it is the "German's favourite child" for façade greening. It can be used to fully cover walls on facades, on masts and poles, and with regular pruning it can also be used for small, limited wall surfaces. In short, this is an excellent plant for any kind of building greening.

Characteristics and Pruning

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 meters and higher, with a yearly growth of 1 - 2 metres. The shoots may hang over. Foliage from May to October. Inconspicuous, tiny green-yellow flowers in early summer, small black berries, wich will feed bees and birds. Summer pruning as needed to restrain the vigorous growth habit, winter pruning as illustrated and described in photos.

Climbing Plant Support System

The Boston Ivy, unlike other "wild grapes" usually has no need for any growth supports. However, in some cases and especially on wind-exposed walls, rope systems (see below) as Easy or Medium Support Systems to 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 stem structure may need to be attached as per rope system 1010.

Further Notes

Boston Ivy can cause significant damage to buildings! The plant grows in a light-shunning way, and, as the shoots increase their stem girth, 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 plants: the only solution is to burn them off / torch them and then repaint the wall!

Full Greening

The following pictures show, how much Boston ivy is suitable for full greening whole walls and buildings!

Way better then on the last picture: Eave is free and not overgrown
Leipzig / Sachsen, University Clinic: Greening on such a massive scale is of course an ideal climbing paradise for insects (spiders!), mice (yes, indeed) and habitat for sparrows chirping away all day. An aspect that deserves thorough consideration... Sti

Partial Greening

Greening buildings and walls only partial by the use uf rigorous pruning, or other techniques - here you can see examples

Green wall in Neuenburg / Saxony-Anhalt
This green façade is particularly charming because the wall is not completely overgrown. Only regular maintenance and pruning will maintain this appearance.
Looks like untamed growth, but mostly greenings like this are the result of rigorous pruning
The japanese creeper conquered alsmost the whole building
Green facade in Halberstadt / Saxony-Anhalt
Facade greening is part of german architecture - even on the German Chancellery
Without constant pruning, this well trained creeper would soon reach the roof
A horizontal cornice forms a barrier to the vigorous growth.

Rigorous pruning made this greenery look so perfect

For maintaining a certain form of the greening, more then one summer pruning is neseccary
This greenery requires 2-3x pruning per year, but still cheaper then a "living wall" of this size
Gera / Thueringen: A Japanese Ivy, obviously re-attached after the restoration of the façade. Here, too, complete cover of the wall can only be prevented with constant care.

Botanical features, pruning and collapsing protection

This picture gallery shows leaves, adhesive pads, flowers, fruits and autumn foliage of the trilobate partenocissus.

Boston Ivy climbs with extremely efficient adhesive pads, hence in Austria, the plant is also called "wall cat"...
After some weeks the adhesive pads are lignified, and then hard to remove from the wall!
Four young plants start conquering a fire-resisting wall
Bees like blooming boston ivy!
Especially eaves are threatened by vigorous growth
If pruning is made to late, the adhesive pads already lignified and cant be removed so easy
Usually the upper parts of a veitchii-greenery are the ones which start coloring fist and therefore become more red in late autumn then the lower parts
Leaf coloration can sometimes be red as opposed to red
Leaf fall in two stages: first the leaves, then the leaf stalks
People often see the appearance in winter as a problem...
If Boston Ivy reaches the roof, then every year at least, a one metre wide strip should be cut free, which is best done while without foliage. If that is not enough, then a summer cut will also be required. Such work is not only time and energy consuming,
Pruning should be repeated every year, because the area cut free will be overgrown in no time again, and the plant will try yet again to get into the eave gutters.
The fruits often last longer then the leaves. To the delight of birds!
Sometimes parts, or even whole greenings can fall off, therefore wire ropes for collapsing protection are strongly adviced!
