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 can be seen hanging from Dirt Blocks if grass has spread there, or from Mud Blocks with Jungle Grass. In either case, there must be empty space below for vines to grow (a Torch or a Wood Platform, for example, will block them). Vines can grow ten tiles downward. Vines can be cut easily with nearly any Weapon or Tool, as the whole vine will instantly be destroyed if the top piece of the vine or the block that the vine is hanging from is destroyed. If that cannot be done, a vine can be destroyed by hitting it with a pickaxe or latching onto the block it is hanging from with a grappling hook. Vines block light, but do not impede movement. The vines can be colored if the block they spawn from is painted.

Unlike tall grass, vines do not require sunlight and will grow underground or in front of walls.

Hallowed vines will spread Hallow, and Crimson vines will spread Crimson.

Vines will never drop the Vine object; this is an uncommon Man Eater drop.

The Guide to Plant Fiber Cordage allows the collection of Vine Ropes from vines.

The Corruption does not have vines whatsoever.

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 very rare quest plant items that can be traded with the Dye Trader who rewards the player with one of 31 quest-exclusive animated dyes.

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.
