Island Decorations are decorative blocks generated on the Biome Islands. All of the infested blocks as well as the Thorny Bush generate in the Infested Forest biome, the Lilyfire tulip generates in the Burning Mountains biome.
Each of these decorations can be planted on End Stone Terrain, End Stone, Grass and Dirt. Just as vanilla flowers and decorations such as tall grass, the Island Decorations require light level of 8 or higher, or direct sunlight to stay alive. This condition does not apply in the End dimension.
Thorny Bush Edit
The Thorny Bush will damage anything that touches it, and has a chance of causing 1.5 to 3.5 seconds of Poison II. It is generated less commonly than other types of infested vegetation, but it is easy to spot because of his darker appearance.
The Lilyfire (an orange tulip) is the only decoration which drops itself when broken, all other decorations need to be sheared in order to collect them.
The Lilyfire can be crafted into orange dye in the same way as crafting other flowers.
