String gardens made with shells. "air plants"
Tiny succulents or starts planted in a variety of shells. The grouping is what really makes this beautiful. Could be called a string sea garden.
Plants upside down in enclosed areas - a very new idea
Succulent Hanging Jars
Mini Hanging Ferns
I don't love the article, but I love the plants in light bulbs! Hanging from a shelf or the ceiling in a corner would be even better!
