Parthenocissus tricuspidata "Veitchii"

The Boston Ivy Vine (also knows 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. 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.

Requirements / Price

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.

Characteristics and Pruning

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 higher, with a yearly growth of 1 - 2 metres. The shoots may hang over. Foliage 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.

Climbing Plant Support System

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 stem structure 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 plants. The only solution is to burn them off / torch them and then repaint the wall!

Full Greening

The following pictures show just how suitable Boston Ivy is for greening whole walls and buildings!

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...

Partial Greening

Partial greening can be created by vigorous pruning or other methods of 'growth retarding.'

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
This Japanese creeper has conquered almost the whole building; what looks like a free-form growth is due to careful pruning!
This green facade maintains dynamism by not covering the facade completely; Halberstadt / Saxony-Anhalt
Facade greening is part of German architecture - even on the federal Chancellery; Berlin
Without constant pruning, this well trained creeper would soon reach the roof.

Clever: growth 'breaks' can also be arranged vertically; in this shopping market, climbing fields are defined by wall breaks/projections.
Well-pruned veitchii
Rigorous pruning made this greenery look so perfect

For maintaining a certain form of the greening, more then one summer pruning is necessary.
This greenery requires 2-3x pruning per year, but is still cheaper then a full "living wall" of this size.

Botanical Features, Pruning and Collapse-Protection

In this gallery, have a look at the 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 lignify, and are then hard to remove from the wall!

Bees like blooming Boston Ivy!
Eaves are especially threatened by vigorous growth
If pruned too late (i.e. autumn or winter), the meanwhile lignified adhesive pads cant be removed so easily.
The autumn leaves often appear in several shades of colour: scarlet red at the top and yellowing at the bottom. Maybe it has to do with shade (shadier at bottom) or with different vitality levels of the plant.
Leaf colour can sometimes become complete orange instead of wine-red.
Leaf fall in two stages: first the leaves, then the leaf stalks
The appearance in winter can be seen as a problem (or at least as an 'eyesore').
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 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 as collapse protection are strongly recommended!
