A lush cave is a temperate underground biome.
Overground, the biome resembles a plains biome[Java Edition only]. 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 in Java Edition, they can sometimes generate inside caves if there is enough room and a lush cave below. In Bedrock Edition, Azalea Trees still generate as normal, however vines also generates on top of lush caves, due to a glitch.
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.
In Java Edition, lush caves can only be obtained through the experimental datapack.
Lush caves include all standard overworld biome features, as well as the "patch_tall_grass_2", "glow_lichen", "lush_caves_ceiling_vegetation", "cave_vines", "lush_caves_clay", "lush_caves_vegetation", "rooted_azalea_trees", "minecraft:spore_blossom", and "minecraft:classic_vines_cave_feature" features. Ambient cave noises are not played in this biome. Bats are the only non-hostile mobs that spawn in this biome. Lush caves use the same sky colour as the river biome. Players cannot spawn in a lush caves biome. The biome's downfall value is 0.5, and its depth value is 0.1. It is classified as an underground biome.
