Vertical gardens. They can be set up on most surfaces both large and small scale. Such as a house, or the on the side of a building, or around the sign of a restaurant. And most definitely on my future home! They can be run on a hydroponic system and don’t require an abundance of extra effort if you think out the correct plants to use and where. Certain plants can shade others etc. The founder is Patrick Blanc, a French botanist.
