My mother-in-law made these from her mother's bottle collection. The bottles were found near old cellar holes- they were discarded by the people who used to live there. We think they're somewhere around one hundred years old. Cleaned up, they make a beautiful display for plant cuttings!
I believe these are pothos! As long as you change the water once a week and get some nutrients in there, I'm told they can stay in water indefinitely.
Thank you! I'll check if I can get some (or similar ones) where I live :)
