Vertical gardens have been around for decades in Modernist landscaping. Now you can bring them to your own home with these vertical garden DIY panels by Flora Grubb. I love succulents, and these installations are modern and beautiful.
You would have to ensure you have the right plants for your climate, and the right wall, but given a bit of thought I am sure different plants would be very successful.
And if you’re very crafty, you may be able to build the wall system at home from scratch.
