Today when I go to do some laundry at the roof top. I spotted this :
Oh Great! Plant on roof top.
As you can see, Japan which have really limited space especially in Tokyo, try to plant everywhere they can. They didn’t have much ground or space for them to plant their flowers in. And so, They try to use all the space they can get to plant their flowers.
Great Idea or Dumb way of doing?
Here is another closer view.
