Once an innocuous grove of carnivorous plants, radioactive fallout and AMS' irresponsible experimentation resulted in a quality upgrade. Once feasting on flies and other insects, the drosera plants have incorporated long pig and other delicacies into their diet.
Creekside sundew grove is essentially a large harvest location for cranberries, brain fungus, and giant pitcher plants, and it is a gauntlet full of mutated animals like gulpers and mirelurks. A Picklock 3 safe can be found near a corpse of a settler within the grove.
The creekside sundew grove appears only in Fallout 76.
