Azalea Field Biome

It could become the most difficult biome to find on vanilla (equal or more than mushroom fields)

Terrain generation with small rivers and ponds of different sizes and depths with clay, moss and mossy cobblestone around

Following the dynamic of azale trees if you only find one tree it means there is a small lush cave underneath, if you find a giant azalea field then so is the cave. There will always be a cave below this biome however a lush cave will not always have an azalea field above it.

The new blocks for this biome would be their own azalea wood and all its variants. Trees with heights of up to 30 blocks with bases of 1 and 2x2. Azalea bushes all around, can be spawned with flowering azalea leaves from 1x2 to 1x10 tall (imitating cypress), mushrooms and grass
