Greenery on walls can reduce a buildings heat loss by 30%, improve air quality, help absorb sounds, and can even reduce a cities temperature, so it is no wonder so many places are considering them.
Here are two options I think are interesting:
Vertical Meadows:
There is a bit of a terminology game here. Verticals gardens are sometimes found in wealthy office buildings, but they do nothing for local eco-systems and are often non-local tropical varieties of plants. Even for those found outside, the plants are often picked for appearance alone, instead of what would help local biodiversity.
In comparison, vertical meadows have a different goal. Vertical meadows (started in London, England) are outdoor vertical greenery walls that uses locally-grown native and seasonal plants, ensuring year-round options for wildlife like pollinators and birds.
The main problem with these setups is that they tend to require watering systems, which (even if rainwater collection is installed) can be rather costly.

Moss Walls:
Companies like Respyre use upcycled bioreceptive concrete and a moss coating encourage moss-growth on any vertical surface without risk of damaging the buildings. Other companies(such as Green City Solutions) grow panels of moss, which can then be installed like tiles.
Due to moss being so inexpensive to incorporate, it is becoming a popular option.
For added benefits, moss is drought tolerant to a point, and can absorb 6x more C02 than other plants. Moss is basically a living filter, and can even filter arsenic out of water.

However, moss can be hard to grow commercially(mostly due to the fact that they release spores instead of seeds), so many of the mosses people buy, especially those used for craft supplies, are illegally poached from the wild. If a little is left behind, moss typically can regenerate, but many harvesters simply roll up huge blankets of moss, leaving nothing behind. It is estimated that the mosses can take 10-20 years to grow back.
So, please research where the moss is sourced if you plan on buying any. If the company does not grow it themselves or does not mention where they source it, do not buy any.
“We cut down all the trees. But hey, we planted a spattering of moss. Totes the same!”
Great news, people, we’ve managed to commodify ivy!
Why let a plant grow on your wall using nothing but a planter resting on the ground and time when you can pay a company to build a giant expensive facade by inflicting decades worth of damage to vulnerable natural environments instead?
I wonder if the vertical walls could be used to grow food for people, there is a lot of possible growing space on a building. An office could rent out their wall space to people or other businesses to grow what they could.
Food seems like it would be difficult to harvest. Anything bigger than a peach might represent a fall risk, as well as any plant that gets big enough that it could hurt someone if it gets ill, rots, and falls to the street. Better to use the inaccessible spaces for small local flora.
Yes, I didn’t think of that aspect. I guess my coconut wall would be deadly.
There was a Curious George episode where George used a skyscrapers (under construction, of course) floor to ceiling wrap around windows to create a vegetable garden so the restaurant down the street had fresh produce.
It wasn’t a bad idea, minus the water damage. Just make a 3 ft planter along all the windows, instead of a window ledge or something, and you would have a ton of food.
