Fussy Azaleas
by davigj
Fussy Azaleas changes where azalea bushes appear, so they grow on bone-mealed moss only in the biomes a config tag lists.
What it does
By default, azalea bushes spawn on bone-mealed moss blocks only inside vanilla's Lush Caves biome. Bone-mealing moss anywhere else no longer produces azaleas unless that biome is listed in the fussy_azaleas:moss_grows_azaleas biome tag. The author made the mod because they wanted moss world generation without reaching Lush Caves on every world, and this keeps moss usable elsewhere while Lush Caves keeps its value.
The config is a biome tag edit: adding biomes to fussy_azaleas:moss_grows_azaleas lets azaleas appear there too, which suits modpacks that add cave or chasm biomes. The mod also sets azalea trees apart from vanilla's less significant azalea trees, which can receive specialized wood types from other mods. It requires Blueprint, and the environment is client and server, so the server and every player need it. It is open source under the MIT License and published for Forge and NeoForge, with files for 1.20.1 and 1.21.1.
Key features
Biome-gated azaleas
Bone-mealed moss yields azalea bushes only in biomes listed in the moss_grows_azaleas tag.
Editable biome tag
Biomes can be added to the fussy_azaleas:moss_grows_azaleas tag so azaleas appear in more places.
Lush Caves default
Vanilla's Lush Caves is the only biome included by default, so the vanilla look stays in caves.
Specialized azalea trees
Azalea trees can be given a dedicated wood type, separate from the less significant vanilla trees.

Use cases
Moss in modded caves
A pack that adds cave or chasm biomes can list them in the tag, so bone-mealed moss yields azaleas there as well.
Keeping Lush Caves distinct
Leaving the default tag untouched keeps azaleas tied to vanilla's Lush Caves.
Who it’s for: Modpack makers and world builders who want azalea bushes limited to specific biomes, and who edit datapack or config tags.

What the author says
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. This mod came about because I wanted to use moss in worldgen without having it guarantee access to azalea trees. While less significant in vanilla…
