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 precious space 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 in a small area. There is also a new trend to even green interior walls; these living wallpapers are called green walls. For the version in your home, flower pots or boxes can be mounted onto the wall and individually greened to create a space-saving planting area.
Whoever thinks about greening facade might use the patented method of Patrick Blanc. A significant benefit of this method is that the destruction of the wall is prevented. For this method 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 and excess water is collected in a tank below the wall and 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.
Built outside or inside, green walls have numerous benefits. They are not only eye-catching and unique but they can also provide a pleasant climate by keeping interior rooms comfortably cool in summer. House walls can also be protected against environmental influences and also from cracks in the masonry that can be caused by expansion during hot 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, particularly next to busy streets.
With newly developed systems, vertical gardens are increasing 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 emitting their benefits in an admirable way.
