Should you call it a botanical miracle, art, or simply a trend? Vertical gardens, invented by the Frenchman Patrick Blanc, are at any rate special and an absolute eye-catcher. The basis for the existence of vertical gardens is the recognition in 1968 that plants indeed need water to survive – but no soil.
Today, vertical gardens show various opportunities for gorgeously greening the cities of the 21st century without occupying rare areas, as they vertically soar into the air on the facades of houses. You can also build hanging gardens on your house wall, on the balcony or on the patio to create a lushly green oasis on a small area. There is also a new trend to even green interior walls. The living wallpapers are called green walls. For the version in your home, flower pots or boxes are mounted onto the wall. Individually greened, a space-saving planting area can be created.
Whoever thinks about greening its facade might use the patented method of Patrick Blanc. A big benefit of this method is that the destruction of the wall is not necessary. For this, a metal frame – which can be back-filled with insulation – needs to be placed at some distance to the house wall. A plastic mat is fixed onto this frame whereon the plants can find hold and grip. Irrigation water and nutrients flow from hoses that are installed on top of the base frame. Remaining water is collected in a tank below the wall and is pumped up again for the next irrigation. From dwarf conifer to rosemary or salvia, evergreen or flowering, countless species of plants are suitable for this sort of plantation. The milder the temperatures, the more varied this masterpiece can be planted.
Built outside or inside, green walls have numerous benefits. They are not only very eye-catching and unique in each case but they also provide a pleasant climate. They keep interior rooms comfortably cool in summer so that, for example, cooling in office buildings can be abandoned. In this way, energy can be saved sustainably. Moreover, house walls are not only protected against environmental influences but also from cracks in the masonry which can be caused by expansion during heat periods. As a matter of fact, green walls namely reduce temperature fluctuations. They also provide higher humidity for open-plan offices, pleasant acoustics and improve the air quality both, inside and outside, next to busy streets. By creating green walls, institutions often try to symbolize a conscious relationship to nature.
With newly developed systems, vertical gardens gain in importance, inside and outside, in the present and in the future. So you will find them more and more often in private homes, waiting rooms, lobbies or office buildings in order to emit their benefits in an admirable way.
