Astroneer Wiki

Hello all editors and users of the Astroneer Wiki! We are in the process of updating and switching over to use the new Fandom Desktop skin on the wiki. There will be many changes over the coming days, but the main goal is to keep the wiki feeling the same, as much as we can! If you notice any issues once the swap is made, please post them to the Admin Noticeboard so we can address it right away. We are also going to be completing the update to the Astroneer Wiki:Style guide, so there is a more up to date guide on how to style the wiki going forward.

Cauldrangea are Biofuel refineries used to combine Sturdysquash Samples and certain Seeds into biofuels for the EXO F.A.R.M. event. Cauldrangea Roots are organic platforms that Cauldrangea spawns on top of, and can be used with Cauldrangea or other items.


Cauldrangea and Cauldrangea Roots could be found on the surface of Sylva, Calidor, and Atrox, protected by hazardous flora depending on which planet they are found on.

Leisurely Cauldrangea are found on Sylva, typically located within the plains biome, surrounded by Lashvine and Bouncevine.

Brisk Cauldrangea are found on Calidor, typically found within the dunes biome, surrounded by Lashvine and Spiny Attactus.

Swift Cauldrangea are found on Atrox, typically in the plains biome, surrounded by Lashvine and Volatile Attactus.


Cauldrangea produce biofuels at different speeds. Leisurely Cauldrangea produce the slowest, while Swift Cauldrangea produces the fastest, with Brisk Cauldrangea's production speed being in between.

The following biofuels can be created at the Cauldrangea:

Output Input
Squasholine Spookysquash Sample x2
Attapetrol Spookysquash Sample
Mutant Spiny Attactus Seed
Noxothane Spookysquash Sample
Mutant Elegant Spewflower Seed


  • "Cauldrangea" is likely a portmanteau of the words "cauldron" and "hydrangea."
