Configured Feature Tags
This content applies only to Java Edition.
Configured feature tags are groups of configured features.
Usage
Configured feature tags can be referenced in biomes to indicate that the biome can generate features of that group. The game also defines some tags with special purposes.
Tag list
#can_spawn_from_bone_meal (8 entries)
If these features are defined in a biome, using bone meal on grass blocks in that biome has a chance to generate these features instead of short or tall grass:
flower_defaultflower_flower_forestflower_meadowwildflowerflower_pale_garden
For the complete member list, see the tag definition under data/minecraft/tags/ in mc_java_sources/, or Minecraft Wiki.
