the most informative article on facade greening practices in Germany (Berlin) and all the benefits of it… So far I have discovered there are 2 PhDs about facade greenery; Bartfelder & Koehler (1987) and Thoennessen (2002), which each study the benefits of climbers to buildings and the urban environment. Things like thermal insulation and dust/ particulate/ heavy metal reduction are some of the biggest benefits, but of course there are others like noise reduction, storm water runoff reduction, biodiversity, etc.
Tendrás por casualidad una lista de plantas que pueden ser utilizadas para hacer un jardin vertical?
uhm… Si! Uhm.. interior o exterior?
You’ll have to forgive me, I don’t speak any Spanish… But yes I am currently making lists for vertical gardens for my research course. I am gathering information from books, magazine articles, gardener’s experience and plant guides and formulating theoretical species lists from there.
There are so many factors that influence what is a desirable species for a vertical garden… If you would like to do a hydroponic system (like those of Patrick Blanc, for example) then you will want plants with a relatively small root mass and you will also want to pick shade loving plants for the bottom of the wall and sun loving plants for the top. A wall is a complex microclimate (especially exterior walls), so for the most luscious looking walls I definitely recommend as much biodiversity as the budget will allow.
There are many options for anyone living is USDA Zone 5 or warmer, but not much for anything colder. This is because the systems being used in most cases are hydroponic, and in climates where the water would freeze for half the year, it’s not going to look good for very long.
Interior walls are the easiest to plan because you can directly control light exposure and mean temperature. This also means a larger plant selection.
I have found a lot of information by simply cruising the internet for species lists and reading scholarly articles about facade greening. Patrick Blanc’s book The Vertical Garden is a great resource if you live somewhere in USDA 9 or warmer, for he lists many species that he uses that grow naturally in the cliff faces of Malaysia and Thailand.
