Compiling a List of all Plant-based Horror Books

[Rechan]

Hello, I'm trying to gather a list of all the horror media relating to plants, for a project from a publisher. This list is for books and short stories.

Beyond The Ruins, Who Goes There? and Day of the Triffids, I'm drawing a blank.

I don't remember Who Goes There being a plant monster. The 1950s movie of it, The Thing From Another World, turned it into a plant monster, but the original story is more like the 1982 movie, more of an animal, but I suppose by the movie's logic it could take on the form of any life including plant life.
