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 seeds. Different biomes generally have distinct plant life.

Herbs
Herbs are used at a Placed Bottle, or an Alchemy Table to craft potions.

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, 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 four different types of vines: Regular vines (grow from Grass and Leaf Blocks), Jungle vines (grow from Jungle grass blocks), Hallowed vines (grow from Hallowed grass blocks), and Crimson vines (grow from Crimson grass blocks). There is no Corruption variant of vines. Vines can only grow above the surface (with the exception of Jungle 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.

Cactus


Cactus grows naturally on Sand Blocks in the Desert biome, and persist even if the Desert becomes infected with Corruption, Crimson, or Hallow. They can be cut down with any axe or by digging the block underneath it with a pickaxe and can be used to make cactus-themed weapons, armor, furniture, or just be placed and used as a building material. Mining the Sand Block underneath it will cause the entire plant to drop. Occasionally, a Pink Prickly Pear will grow on top of cacti.

Thorny bushes
Thorny bushes are plants that grow naturally in the Corruption, the Crimson and the Underground Jungle. Thorny bushes will damage the player on contact. Currently, there are three types of thorny bushes. Brown bushes that grow in the Underground Jungle deal 25 damage. Purple bushes and red bushes grow in the Corruption and the Crimson respectively, and deal 10 damage each. Thorny bushes are destroyed after contact with a weapon or tool. Invisible projectiles (Medusa Head, Life Drain etc.) don't destroy thorny bushes. Thorny bushes can grow six tiles in all directions. All NPCs and enemies are immune to them. They cannot be obtained as an item. The Corruption and Crimson variants spread the Corruption/Crimson. The Jungle variant, however, does not spread jungle grass. The growth of thorny bushes is blocked by vines, allowing for vines to block the spread of Corruption/Crimson via bushes.

Sunflowers
Sunflowers are a surface plant that prevents the spread of The Corruption and The Crimson on the blocks they are planted, provides the normal biome atmosphere, clarifying up the ambient, and gives the Buff to players in a 50-tile radius, increasing movement speed and reducing monster spawn rate in a minor effect.

Life Fruit
Life Fruits can be consumed to permanently increase the player's Health by 5 points, up to a total of 500 (20 used). They are found in the Jungle during Hardmode / after defeating one Mechanical Boss. Life fruits become more common once more Mechanical Bosses have been killed.

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 one of 33 animated dyes, all but two of which are quest-exclusive.

Plantera's Bulb
Plantera's Bulb is a pink plant in the Underground Jungle that will begin to appear after all 3 Mechanical Bosses have been defeated in that world. It will summon Plantera when broken. Though it cannot be broken by 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 In-Game half-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.
