We always think of window box planters affixed to the outside of a house or on a balcony, but why not reverse the look and try one inside instead? A long, narrow planter like this could be used, for example, in place of a table, to solve the problem of how to place a couch or a bed up against a window without creating weird lines or an unsightly gap. Can't you just imagine the little succulent tips poking up behind the top of a couch?
Alternately, if you've got a banquette, you could try replicating the garden from Nopalito in your dining nook, even using landscape lamps among the plants as accent lighting for romantic meals.
Here's another one, previous featured on Apartment Therapy: LA, that's purely decorative. What do you think of the look? Would you try this?
