Vegetation

Vegetations are features composed of plants including grass, ferns, flowers, and mushrooms in the Overworld and the Nether.

Vegetation generates a semi-random amount of certain blocks in a small area. Vegetation can only generate on blocks that are supported by the consisting blocks; e.g. short grass can only be placed on dirt and variants. However, some plants of a vegetation feature can generate on blocks that are only supported by some plants, namely sand and gravel.

Most of these features can only generate on the surface, rarely leaking into caves. A few like sugar cane can only generate bordering water, and some can generate anywhere exposed to air.
