Grasses
Grass is a type of block which covers most of the above-ground landscape. It enables many different plants to grow on it.
Natural grass types
These types of grass occur naturally throughout the world. They can also be planted manually with their respective seeds. Regular grass can furthermore be planted with the Staff of Regrowth or Axe of Regrowth(Desktop, Console and Mobile versions).
If there is room below a grass block, the respective type of vine can grow downward from it. Acorns planted in grass (except Mushroom grass) will grow into the respective type of tree.

Wild plants on grass
These weeds and flowers grow naturally on the different types of grass on the surface. They do not grow below the surface (except on Jungle, Mushroom, and Ash grass), and do not grow on mowed grass. Plants growing on painted grass blocks will take on the block's color (except large Jungle plants).
Some of these plants can be planted manually with Flower Seeds(Desktop, Console and Mobile versions), Flower Boots(Desktop, Console and Mobile versions), and the Rubblemaker(Desktop, Console and Mobile versions). The rest cannot be planted manually.

When trying to grow some types of plants, the tile of the soil block and the tile above the soil block must not occupied by walls, or occupied by one of the walls listed below.[1]

Spread
Grass of any type spreads from existing blocks to other blocks of the correct soil type. The following restrictions apply:
- Pure, mowed, and mowed Hallowed grass does not spread below the surface whatsoever.[2] The player needs to be at least at 4 feet (on the Depth Meter) on the surface for these types of grass underneath to be able to spread.
- Grass only spreads to an adjacent block, i.e., a block within the eight tiles directly surrounding the grass block.
- Grass does not spread to blocks that have lava in one of their adjacent tiles.
- Grass only spreads to blocks that have at least one tile of open space within their adjacent tiles (i.e., grass does not spread to blocks that are fully surrounded by eight solid blocks).
Additionally:
- Dirt Blocks and Mud Blocks are both eligible soils for both types of the evil grasses. For instance, Corrupt Jungle grass can spread onto Dirt Blocks (resulting in regular Corrupt grass), and regular Corrupt grass can spread onto Mud Blocks (resulting in Corrupt Jungle grass).
- The mowed grasses also spread to adjacent Dirt Blocks (only above the surface), but the resulting new grass will not be mowed.
- Painted grass will spread its paint, too.
- Corruption and Crimson thorny bushes can create Corrupt/Crimson grass on adjacent Dirt Blocks !!Error: Invalid EICONS input! and Corrupt/Crimson Jungle grass on adjacent Mud Blocks.
Tips
- When mining blocks with grass, the grass will absorb the first hit from the pickaxe/drill. Hence, unlike mining most blocks, a tool with high mining speed will actually always outperform a slower tool, even if the slower one has higher pickaxe power. This means that the best pre-Hardmode item for digging grass would be the Bone Pickaxe. In theory, the Shroomite Digging Claw(Desktop, Console, Old-gen console and Mobile versions) has the best speed out of the Hardmode tools.
- This becomes particularly important in the Jungle biome, due to the prevalence of Jungle grass.
Trivia
- There are unused graphics for two other grass types in the game's files,
Tiles_2_Beach.xnb
andTiles_199-gross.xnb
. The former one is a yellow-green grass akin to Jungle grass, although it is tiled on dirt, which might be originally a grass variant for the Ocean. The latter one is a variation of Flesh Blocks, tiled to work as a grass.- Crimson grass is referred to as
FleshGrass
internally, so the second grass variation may have been an early Crimson grass sprite.
