This plant has been growing in a pot of something else for a long time and I never knew what it was, I'm not even sure where it came from. It's nice to have a name though, and I am thinking about giving it its own pot. I don't want it to escape into the garden as it seems like it could be invasive in this climate. So far it has only lengthened one strand, it's now about 4' long. It has never made another branch? Perhaps I should cut the long branch into pieces and let them root.
