Hello all,

regarding vertical plants,
some examples against air pollution came to my mind.
it's not really "farming", but at least an "artificial" way to grow plants,
so it doesn't really fit with "natural"

Do you think this should be considered ?

I could imagine to extend this tag for it :
http://wiki.openstreetmap.org/wiki/Tag:landuse%3Dvillage_green
Something like this ? :
landuse=village_green
landuse:type=vertical
landuse:horticulture=lichen,moss
