Overview
This is an incredibly niche mod with one feature: azalea bushes do not spawn from bone-mealed moss blocks, unless the bone-mealing takes place in a certain biome tag.
The need for this arose because I wanted to be able to use moss in modded worldgen without having it guarantee access to azalea trees. While azalea trees aren't significant in vanilla, mods such as Caverns and Chasms add an azalea woodtype actually worth discovering. Thus, I wanted to let the Lush Caves retain that value while still employing moss for my own nefarious means.
Config
While there is no config, you can edit the biome tag fussy_azaleas:moss_grows_azaleas
to add more biomes where azaleas should be available. By default, this only includes vanilla's Lush Caves.
Requires Blueprint. Feel free to direct any compat suggestions and bugs to the issue tracker!
