Ambrosia bush

Ambrosia bush

A rare wild bush which yields the ambrosia fruit. Ambrosia fruit is delicious and produces a drug-like mood boost. Ambrosia cannot be farmed, which makes wild ambrosia groves very valuable.
Its rarity, beauty, and desirability are why ambrosia was named after the food of the ancient Greek gods.

Ambrosia bushes are an exotic plant in RimWorld which only naturally occur through the ambrosia sprout event, and therefore can't be grown by the player. A mature ambrosia bush yields Ambrosia 4 ambrosia.

The event can only occur, and thus the bush can only be found, in the following biomes:


Ambrosia bushes have a base growing time of 6 days, need a minimum soil fertility of 30%, and have a fertility sensitivity rating of 15%. The following table details how long it takes for Ambrosia to grow in each growable ground type, factoring in the plant resting time and being in ideal growing conditions:

  • Ground Type Gravel Soil Rich Soil Hydroponics
    Fertility (%) 70 100 140 280
    Real Grow Time (days)[1] 11.6 11.08 10.45 N/A
    Base Yield/day[2] 0.34 0.36 0.38 N/A
    1. Actual days to grow, taking into account rest time.
    2. Per plant, assuming Crop Yield Multiplier of 1.0.
      Note that Difficulty settings change the Crop Yield Multiplier.
  • Unlike most plants, the harvest yield is determined by the drug crop harvest yield stat of the harvester. This stat is still primarily determined by plant harvest yield.


    Ambrosia is a valuable fruit that can be consumed once every 2 days for a +5 mood boost, or sold to traders. In order to have colonists automatically harvest ambrosia, you can create a growing zone on top of all the bushes. Disable sowing, but keep plant cut enabled. Once the bushes have finished growing, they will be cut by growers.

    Each ambrosia fruit is more valuable than flake, and each bush has a base yield of 4 fruits. As there's no need (or ability) to process ambrosia any further, a nearby ambrosia sprout is an efficient way to make a bit of extra cash. However, it isn't worth it to travel halfway across the map in order to satisfy an ambrosia fix.


    According to the Cryptosleep Revival Briefing, ambrosia bushes are apparently engineered to have a pleasurable, drug-like effect on those who eat it. On some planets, its wild variants have adapted to a strategy whereby they provide pleasure-inducing fruit in exchange for care from animals and people.
