Plants

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

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 the vine to grow (a Torch or a Wood Platform, for example, will block them). 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 are destroyed. If that cannot be done, a vine can be destroyed by getting hit by a pickaxe or having the block they are hanging from be latched to by a grappling hook. Vines block light, but do not impede movement.

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

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

Hallow vines will spread hallow, and Crimson vines will spread the Crimson.

Cacti



 * Main article: Cactus

Cacti can be found in the Desert biome on sand. They can be chopped down, like trees, to receive Cactus. However, unlike trees, you can mine the sand from beneath them, which will destroy the cactus. Hallowed, Corrupt, and Crimson cacti will still drop the cactus item.

Thorny bushes


Thorny bushes are plants that grow naturally in the Corruption and the Underground Jungle, like grass. Unlike grass though, Thorny Bushes will damage the player on contact. Currently, there are two types of thorny bushes: red bushes that grow in the Underground Jungle which deal 25 damage and purple bushes that grow in the Corruption that deal 10 damage. Thorny Bushes grow in all directions (not just upwards), and may spread. All NPCs and enemies are immune to them. They cannot be obtained as an item. The Corruption variant of Thorny Bushes spreads corruption, the Jungle variant, however, does not spread jungle grass. Thorny bushes cannot grow over or otherwise affect vines. Therefore, vines can prevent the propagation of Corruption across large gaps that would otherwise require careful maintenance. However corrupt bushes will convert jungle bushes in hardmode.

Sunflowers

 * Main article: Sunflower

Sunflowers are found on grass on the surface. They are not only there for decoration, but they also stop corruption and crimson from spreading. You can pick them up by destroying the grass on the block under them with a pickaxe to receive a Sunflower.

Life Fruit

 * Main Article: Life Fruit

Life Fruit are found only in the Jungle Biome during hardmode. They can be collected by swinging a sword or pickaxe to destroy it like grass or thorns. Life Fruit are consumed for a permanent increase of 5 to a players maximum Health.

Dye Plants


Dye plants produce or transform into dye materials when harvested. They grow in various regions depending on the type of plant; see dye for more information where to harvest each one.
