Interiorscape - what does that mean and is it a real word? If you look on Wiktionary you will find this definition "interiorscape (noun) An installation of plants decorating the inside of a building." That describes it quite well. So, you can find companies that sell indoor plants, companies that will take care of your plants for you, or help you design your very own indoor plant sanctuary.
