Does grass spread in the nether?

Question

I recently started a hermit chunk and managed to get a grass block from an enderman and obviously don't want to waste it. Searching the internet for an answer has been fruitless.

Answer 1

Yes. Grass will spread from grass blocks to dirt in all biomes and all dimensions, including the nether

Answer 2

It will as long as a light source such as a torch beside the grass is there to allow it to spread. (as of Java 1.16.5)
