Морозник

The Aquapanthus uses a very small amount of mana to fill nearby cauldrons and petal apothecaries with water. It can also fill some other fluid containers that are mostly unknown to the average botanist.

The Exoblaze uses mana to fill the fuel of nearby brewing stands. Never put blaze powder in again when brewing your potions. It's still a pretty primitive flower, as powerful botanists have better devices than brewing stands...

Piglins and Hoglins usually transform into zombies when in the overworld. While the exact reason is not yet known, botanists have found a way to use mana to keep these creatures safe. Any Piglins or Hoglins in range of the flower won't zombify when the nether, as long as the flower has sufficient mana.
