Sunflower



Sunflowers are large flowers capable of preventing the spread of The Corruption and The Crimson. Sunflowers are not able to stop the Hallow. They act as background objects like furniture and can be collected with a pickaxe. They are also sold by the Dryad.

Sunflowers can only be placed on Grass and Hallowed Grass at any height. They cannot be placed on Corrupt Grass, Crimson Grass, or Dirt. They cannot be planted in a plant pot. They have a very low chance of spawning more sunflowers in a small area. No background walls can be present when the sunflower is planted, but walls can be placed after the sunflower is placed.

Placed Sunflowers contribute to decreasing the unseen total that causes NPCs to reject housing due to the presence of The Corruption or The Crimson. If placed in large quantities, they can allow NPCs to live near tainted blocks.
