There is a company called " Living Wall Company" which specializes in building vertical walls to grow plants.
This does several things, depending on where the wall is.
You can grow food plants in them, if they are away from the road so they don't get polluted.
They help cut down on the heat generated by walls being baked by the sun constantly.
They look better than a plain concrete or brick wall.
They retain the soil behind them better due to the roots of the plants growing into them. |
