The Ghost Weed is a flora species, found in deep biomes. It can be harvested for Ghost Weed Seeds by using a knife.


The Ghost Weed boasts a peculiar appearance. It has a green and red bulbous base, followed by two long green stems, each with several small protrusions near the tip and three short red stems, giving off a dull bioluminescent glow.

Data Bank EntryEdit

Ghost Weed-0

Grows exclusively in regions populated with blood kelp, and shares some genetic similarities.



  • The Ghost Weed was originally called the Red Green Tentacles.
  • Despite the data bank entry stating that this species grows exclusively in regions populated with Blood Kelp, this is not true in game as Ghost Weed can be found in the absence of Blood Kelp in Lost River.
