Staff of Regrowth

The Staff of Regrowth spawns Grass on Dirt blocks, and also functions as a low-tier (albeit quick) Broadsword. It can be found in the Underground Jungle Biome in Shrines.

The Staff may grow grass on any Dirt Block, no matter how deep it is. Unfortunately, grass has limited function underground. Past a certain point, Grass will not grow weeds or Dayblooms, and Trees will not mature.

The Staff of Regrowth functions well as a trail marker Underground, as grass stands out well in the environment of grays and browns.

Despite being found in the Jungle, the Staff does not grow jungle grass on mud blocks.

The staff however is very useful in hard-mode, as it can be used to spread hallowed grass underground.
