Lush Caves

Planned

A lush cave is a temperated underground biome.

Description
Azalea trees generate on any empty space above a lush cave, with roots consisting of rooted dirt and hanging roots that generate down until reaching the lush cave. This is most common at the surface, but they can sometimes generate inside caves if there is enough room and a lush cave below.

Underground, moss covers the floors and ceilings, along with moss carpets, grass, and azalea bushes on the floors. On the ceiling cave vines with glow berries grow down and light up the caves, and spore blossoms grow from the ceiling and drip particles. It also contains clay pools where dripleaf plants grow out of them.

Lush caves currently cannot generate naturally in normal worlds but can be generated with a buffet or custom world type.
