My friend has a lanky bamboo in a glass jar sitting in my hall for some weeks without water. All is left are some roots, perhaps dried?
I thought that it's not gonna survive but it's still having all its green leaves with a couple of brown ones, and still surviving! The trunk is wrinkled though.
I'm thinking of asking my friend to let me plant it outside in the garden. I heard that bamboo is invasive and spread easily. So I'm not sure whether to plant it, if that's the case...
