Plants

Plants are found all across a Terraria world, and may grow from certain block types given various conditions. Most can be harvested for use, and may additionally drop seeds for replanting, such as Jungle grass and your world evil grass seeds. Different biomes generally have distinct plant life.

Moss
Moss is a grass-like plant that grows on Stone Blocks. It comes in several different colors and can be found either randomly on Cave surfaces or in moss chambers with a matching mossy wall. Moss sprouts fuzz that can be cut like grass weeds. On the, it can be collected as an item using a Paint Scraper and used for replanting or crafting mossy walls.

Herbs
Herbs are used at a Placed Bottle or an Alchemy Table to craft potions. They can be found all across the world, or in, and can be harvested with almost any weapon or tool. Each herb will bloom when certain requirements are met. Herbs harvested while blooming will drop 1-3 seeds of their kind in addition.

Mushrooms
Regular Mushrooms can be turned into Vile Mushrooms and vice versa using Purification Powder, Unholy Water, or Holy Water, respectively.

Vines
Vines are plants that grow downward from blocks. Given there is enough empty space, they can reach a length of up to ten tiles. Although they block light(excluding Glowing Mushroom vines, which produce light), they do not impede movement and can easily be destroyed with nearly any weapon or tool. Destroying a tile of a vine destroys all tiles of the vine below it and destroying the topmost tile or mining the block it hangs from will destroy the entire vine.

There are six different types of vines: Regular vines (growing from Grass and Leaf Blocks), Flower vines (growing from Grass in grassy caves, or in front of player-placed Grass or Flower walls), Jungle vines (growing from Jungle grass blocks), Glowing Mushroom vines (growing from Mushroom grass), Hallowed vines (growing from Hallowed grass blocks), and Crimson vines (growing from Crimson grass blocks). There is no Corruption variant of vines. Vines can only grow above the surface (with the exception of Jungle and Glowing Mushroom vines which can grow at any elevation) and only from blocks that are not sloped on their underside.

Vines can be painted. New vines growing from painted blocks will take on the color of that block and vine tiles spawned by naturally extending vines will take on the color of the existing tip of the vine. In Hardmode, Crimson and Hallowed vines qualify as spreading tiles in regard to biome spread. The allows the collection of  from vines.

Vines will never drop the Vine object; this is an uncommon Man Eater drop. In spite of this, Glowing Mushroom vines will drop Glowing Mushrooms when destroyed.

Cattails
Cattails are plants that grow naturally on blocks submerged underwater 1-7 blocks deep. They are background objects and can be destroyed with most weapons or tools, but only Glowing Mushroom cattails yield drops. They can grow up to 1 tile above the surface of the water. Destroying a tile of the cattail will destroy all tiles of the cattail above it and destroying the base or block it's attached to will completely destroy the cattail.

There are 6 types of cattails: Regular cattails (growing from Grass), Jungle cattails (growing from Jungle grass and Sand Blocks in an Oasis), Hallowed cattails (growing from Hallowed grass), Glowing Mushroom cattails (growing from Mushroom grass), Corruption cattails (growing from Corrupt grass) and Crimson cattails (growing from Crimson grass). Excluding Glowing Mushroom cattails, cattails can only grow above surface level.

Glowing Mushroom cattails drop Glowing Mushrooms when destroyed.

Lily pads
Lily pads are plants that grow on the water's surface above suitable blocks. They are background objects and are destroyed by most weapons and tools.

There are 5 types of lily pads with 18 variants each adding up to a total of 90 lily pads. These are: Regular lily pads (above Grass), Jungle lily pads (above Jungle grass and Sand Blocks in an Oasis), Hallowed lily pads (above Hallowed grass), Corruption lily pads (above Corrupt grass) and Crimson lily pads (above Crimson grass).

Cactus


Cactus grows naturally on Sand Blocks in the Desert biome, and persists even if the Desert becomes infected with Corruption, Crimson, or Hallow. They can be cut down with any axe and can be used to make cacti-themed weapons, armor, furniture, or just be placed and used as a building material. Occasionally, a Pink Prickly Pear will grow on top of a cactus. In and before, mining the Sand Block underneath a cactus will cause the entire plant to drop, but since  this is no longer possible.

Jungle Vegetation
Jungle vegetation are plants that grow naturally on Mud Blocks in the Jungle and Underground Jungle biomes.

Destroying vegetation in a Surface or Underground Jungle Biome has a chance to spawn various Bait Critters that can be collected with the Bug Net (Worm, Grasshopper, Grubby, Sluggy, Buggy).



Oasis Vegetation
Oasis vegetation are plants that grow naturally on Sand Blocks in the Oasis biome. Tile ID-530

Bamboo


Bamboo grows naturally on Jungle grass that is submerged under water 2-5 blocks deep. It grows in straight columns at a very slow rate. Bamboo can be cut down with a pickaxe and can be used to make furniture or Large Bamboo.

Tile ID- 571

Seaweeds


Seaweeds are plants that naturally grow on Sand Blocks submerged under water at the Underground layer, most notably in Ocean Caves.

Sea Oats


Sea Oats are plants that naturally grow on Sand Blocks in the Oasis and Ocean biomes.

Thorny bushes
Thorny bushes or thorns grow naturally in the Corruption, Crimson and Underground Jungle, and will damage any player on contact. There are currently three types of thorny bushes: brown bushes from the Underground Jungle deal 25 damage; purple and red bushes from the Corruption and Crimson, respectively, deal 10 damage each. Thorny bushes are destroyed after contact with a weapon, tool or the player, but invisible projectiles (Medusa Head, Life Drain, etc.) do not destroy them. All NPCs and enemies are immune to them, and they cannot be obtained as an item. Thorny bushes can grow six tiles in all directions, although their growth is blocked by solid objects and various other scenery. The purple and red variants spread the Corruption/Crimson; the brown variant, however, does not spread Jungle grass.

Sunflower
Sunflowers are surface plants that prevent the spread of the Corruption, Crimson ( and Hallow) on the blocks they are planted, and provide the buff to nearby players, mildly increasing movement speed and reducing enemy spawn rate.

Life Fruit
Life Fruits are consumables that permanently increase the player's maximum health by 5, up to a total of 500 (If 20 are used). They are found in the Underground Jungle after defeating at least one mechanical boss / during Hardmode. Life Fruits become more common once more mechanical bosses have been defeated. Life fruits will glow under the effect of spelunker potions.

Dye Plants
Dye Plants can be crafted into Dyes at a Dye Vat. They can be encountered in various biomes, and show on the map.

Strange Plants
Strange Plants are uncommon quest items that can be traded with the Dye Trader, who rewards the player with 1 out of 33 special dyes in accordance to which bosses and/or events have been defeated. Only two dyes are not quest-exclusive (the player receives a quantity of 3 of the randomly chosen dye type).

Plantera's Bulb
Plantera's Bulb is a pink plant in the Underground Jungle that will begin to grow after all 3 mechanical bosses have been defeated (1 will suffice on the 3DS version) and the world is in Hardmode. It will summon Plantera when mined with a pickaxe/drill, broken by explosives, hit by a Clentaminator with Solution, or if the jungle grass under it is hammered or converted to another block. Though it cannot be broken by other weapons or projectiles, caution should still be taken if these conditions are met to prevent any unwanted boss fights. One bulb will spawn about every six minutes (roughly one quarter of an in-game day.)

Pumpkin
Pumpkins grow naturally during Halloween and can be planted with Pumpkin Seeds sold by the Dryad. It can be placed as well as crafted into armor, furniture, walls, and Pumpkin Moon Medallions. There is also a chance to get the Magical Pumpkin Seed.
