String gardens are essentially plants that are contained within a ball of peat moss and bonsai soil, and then wrapped in twine and moss. Plants used range from wheat grass to hydrangeas to kumquat trees and beyond. Hung from a ceiling of a room or outdoors along a trellis, they're surprising little treasures. While you can buy them at Pompon in Amsterdam (I spied this one at a pop-up shop in a chic boutique district), you can also make them yourself, too. There are plenty of great tutorials online, including this one from Design Sponge. Tell me, have you tried to create a string garden yet?
