Automakers have made attempts to create more environmentally friendly factories before. Subaru even leveraged its zero landfill factory in Indiana as part of an advertising campaign.

Automakers have made attempts to create more environmentally friendly factories before. Subaru even leveraged its zero landfill factory in Indiana as part of an advertising campaign. But Toyota looks to have raised the bar to a new height by engineering two new flowering plants to help clean the air at its Prius Toyota City factory in Japan.

The new flowers are derivatives of the cherry sage ans gardenia plants and were specifically chosen for their ability to absorb nitrogen oxides and convert them to water vapor. Toyota is hoping that the net result will be cleaner air and lower temperatures around the factory.
