Whoever plans a wall greening sometimes notices that she stands alone in the neighborhood on the leafy house concept. Houses are not greened anywhere to be seen! The following question arises: Actually, where are the many green facades which can be seen on all the photos in this website? Is our own location suitable for a green up at all perhaps? And : In which continents is greening walls common? You can find answers on this page. In the next topic of "ideas" we discuss greening up styles and types and the sizes of green wall surfaces.
Seen globally building greening is particularly spreadout in Europe primarily in areas with a moderate climate, i.e. medium warm summers and mild winters. It has tradition, especially with the Christian wine culture, here in Europe for centuries. There is a special microclimate in the German viniculture areas which offers optimal locations for wall greening up.
The plant choice is limited by the hard frosts in cold areas which aggravates a permanent facade greening. The plant choice is more varied in warmer regions but many species cannot survive pinned to hot walls! The trend there is to move away from the walls and create shade forming canopies with greenery. Pergolas and such plants are perfect. The result is less heat stress for the plants.
It could be the contents of a research paper to map the main regional focus center of facade greening worldwide.
In the middle and south of Great Britain green facades are very well known! Maybe it is "THE" land of the facade greening with its beautiful greened castles, country estates, and farmhouses. Presumably the mild and balanced climate (Gulf Stream) plays a large role here. The European heartland of France, Germany, Austria, and Switzerland- as well as the Benelux states, and the southern East European states up to the Ukraine follow after. The climate is often already too harsh in East European countries like Poland and Russia for a perfect green facade. In Southern Europe the houses and building walls, however, frequently get very hot and effect the plants there.
But alone the climatic zone isn't the deciding factor. The mentality of the people also plays a role. Even in a noble, well situated city you may be able to travel kilometers and not see a green facade or flowers anywhere, as well as in a"well kept" but sleepy suburb settlements. Alternatively, there are smaller cities who depend on tourism and they will in turn enhance their appearance with attractive greenery. Many houses or whole street are greened up there. The so-called "Rose Cities" are an example. And this is sometimes the way one must first start and the neighbors soon follow ....
Here you can find photos and also in the main sector of"ideas" and "climbing plants" from Saxony, Saxony-Anhalt and Thuringia. There are many views from the Saxon Elbe valley around Dresden, Radebeul and Meißen and Bad Langensalza from the region Naumburg and Freyburg/Unstrut but also the citiy of Weimar, Halle/Saale, Leipzig, Grimma, Sangerhausen, furthermore Potsdam, Berlin and Cottbus are often represented here. The motifs usually come from the public street spaces. In historically significant buildings the location is sometimes noted, if applicable, and then only visible if you move your mouse over the photo.
You can also find pictures in the area of growing systems/cable systems which customers left to us to use anonymously.
Also in the European mountainous areas building greening can be found north of the Alps up to about 600 m altitude and south to 1,000 m and above. At higher altitudes, the winter frost and wind can cause problems.
Temperate climates also exist in other continents, for example in North America. Here, however, green facades are probably not a significant phenomenon, perhaps because the population is less settled and rooted and fewer stone heavy houses are built. Also, China and other parts of Asia are climatically suitable.
