A grape vine indoors? Twig says yes, and they've tested it out! The ivy complements it well, since it hangs low to the base and adds to the ethereal look. String gardens are made using the Japanese bonsai technique of kokedama, along with a little bit of soil science. Simply take out of the box, soak, and hang. Grape vines are a favorite because of their big, beautiful leaves. Try to keep it next to a wall with a window if you want to see it climb. At about two feet, they ship small which keeps them safe until they reach their home.
