Ghost of Nang Fa Thani (1967)

Just your standard tale of an angel cursed by God to live on Earth as a banana tree who then returns as a ghost to haunt and kill those who cut down said banana tree. She also falls in love with a moral man. Unfortunately, he prefers the romantic company of a human woman over that of a banana tree ghost so she threatens to destroy an entire village. I mean, the nerve of some people!
