Plant Species R
Genesis 2 Tentacle Crops
Added in

Plant Species R is a plant in the Genesis: Part 2 DLC of ARK: Survival Evolved. This "plant" is a thicket of meat that wriggles around upon growing up, acting as a cuttable supply of meat when harvested.

Most methods works as if you are cutting down a tree, but the method does not have any impact on the amount of meat gathered.


If you can get past its tentacular looks, this mutant hybrid seems useful as a foodsource...
You can grow it from seeds, but it provides edible meat.
Another of Rockwell's genetic modification experiments, I guess.

The Plant Species R grows the same as any other plot-based plant, consuming both water and fertilizer to grow. Its Plant Species R Seed (Genesis Part 2) seed may be planted only in a Tek Crop Plot (Genesis Part 2) Tek Crop Plot (Genesis: Part 2).

The following items can be used as fertilizer:

* When a plant has its maximum of fruits, it needs less fertilizer. As the fruits spoil after some time, leaving the plant in a non-full state for some time, these numbers are rather theoretical maximums.


  • It is the fourth plant species to be released, proceeding the plant species X, plant species Y and plant species Z
  • The ‘R’ in its name is a reference to Rockwell
  • Using a Higher Quality Metal Pick Metal Pick to Harvest the Plant DOES NOT make a difference to the amount harvested, Only how long it takes to do so. (High Quality Pick =Quicker Harvest)
  • When Harvesting Plant Species R, you will see a 'Health Bar' that decays as you hit it with a pick. Don't be afraid to deplete this bar, as it will not destroy the crop, Instead the tentacle will shrink and begin a 30 minute timer, at the end of which it will pop back up with all its health, ready to be harvested again.
  • If the plant is left with some but not all of it's health bar depleted, it will still take 30 minutes to regain it's health (regardless of the amount). Therefor it's much smarter and more beneficial to harvest it in full rather than leaving it half harvested as you gain nothing from doing so.
  • It is worth noting that if playing on an unofficial server with structure damage turned off, it can become impossible to harvest. It is currently assumed for this to be a bug, however it is unlikely to ever be fixed. ~Slight fix for this below.
  • On PvE servers PvPEnableFriendlyFire might have to be enabled for players to be able to harvest the seeds.
  • Chainsaw Chainsaws can be used to harvest it.
