An azalea tree is a rare tree that can generate above a lush cave biome, marking the biome's presence aboveground. They extend their roots underground into the cave beneath.


Azalea Tree with Roots

The rooted dirt and hanging roots that generate under an azalea tree.

Azalea trees generate on any empty space above a lush cave, including in biomes that are not grassy or underground.[1] Their roots consist of rooted dirt and hanging roots that reach all the way down to the lush cave at cavern systems such as ravines and abandoned mineshafts. The trees appear most commonly at the surface, but they can also generate inside caves given that there is enough room.

Using bone meal on an azalea or flowering azalea may grow an azalea tree, replacing the block where it was grown with rooted dirt. It does not need to be over a lush caves biome, instead working in any biome like saplings.
