What is the zone and can you name the primary vine? Thank you

The area is the Sierra foothills near Visalia, CA. there are no vines. Many many little plants!

Is this possible in the dessert? I.e. New Mexico or Arizona

yes, but you should do a test run before building something big.

Can you please explain me how to build the green wall. Is it a complicated system? Has too much maintenance? Is it expensive? Sorry all the questions...!

It is mesh boxes of earth bolted to the wall with an air gap behind and recirculating water through a drip system. Build, test, try out native plants at the same exposure as you intend for the finished product, then form your own conclusions. As with all architecture and landscape, it is important to be site specific.

Thanks for much for your answer. I´d like to build one in the country yard in Argentina. We have all seasons. Could you help me to do one? Need specific directions. Its a 10 x 3.5 meters wall. Thanks for all!

the wall was designed by rana creek- chewck out their website.

Is that solar cells I'm seeing on the roof?

Beautiful work. You must be very proud of your work.

Yes, those are solar cells on the roof. The building roof is sloped to match the optimum sun angle for that location.
