Flowers are soothing and refreshing. They have the ability to lighten you mood of the day. Having bunch of flowers in you house will make you feel better. However, flowers in the city I guess at this time are just a dream. City houses have very limited space to plant and maintain some flowers.
Nevertheless, these limitations did not stop Mac Carbonell from pursuing his project for the Flowerbox Building on LES. He did the landscape design for the building and has 500 plants with 80 different species. You may want to check the place for yourself and realize that flowers still have their space in the City.
