Any plant enthusiast will know garden terrors as destructive insects like aphids and spider mites. But on the horror screen, plants are just as killer! In this collection of films, horticultural horrors like franken-plants, vicious vegetables, and freaky fungi are all nightmare material. If you’re not sure where to begin, I recommend The Freakmaker (1974), a film (featuring LOTS OF PLANTS) about a scientist who experiments with crossing plants with humans (available to stream on Prime Video).
