Hi, which plants can grow on walls?

Some years ago when i was in Berlin i saw in some places walls with plants growing on them covering all the wall.

Im gonna build a house using superadobe technique and i was wondering if its possible to have all the external walls of my house with plants growing on the walls.

Which species can be useful ?

Im in arid tropical environment in the southern hemisphere.



thanks in advance

How would you like the plants to live on your wall? Would they hang off the roof? Would they literally be connected to the wall?

Vines are good if you answer yes to the second question. Epiphytes and mosses would be good if you say yes to the third question. Other species could fit in if you think of another way to use a wall in the first question.

When you say "superadobe", are these, here and here, what you are talking about? If this is as strong or stronger than concrete, bricks, cob, or mortar, I do not see too much of a problem. What are your observations about "superadobe"? I would like to know more about it. As with all things, water is a powerful element. What are your current thoughts on protection from weathering and erosion?

I think it may have been a work of Patrick Blanc.

He builds a structure in front of the wall but if you search for living walls you find other systems too.
I love his work and like to visit his works when traveling.

The ones that i have seen doesnt have that structure.

Heres a pic i found, do anybody have an idea which plant is that? or which plants can give similar effect?

Plants in the Parthenocissus genus on that wall. Hard to tell from this angle, but probably Japanese/Boston Ivy (Parthenocissus tricuspidata)
