Roots

Roots are a non-solid plant block that come in two variants, crimson roots and warped roots, which generate naturally on warped or crimson nylium in their respective biomes.

Natural generation
Crimson roots generate in the crimson forest biome and rarely in the soul sand valley and warped forest biomes. Warped roots generate in warped forest biomes.

Post-generation
Applying bone meal to nylium causes roots to appear on that nylium block, and on nearby nylium. The roots are always the same type as the nylium (e.g., crimson roots appear on crimson nylium).

From block loot
Roots can be mined instantly with any tool. They drop themselves when broken, and can be placed on nylium and in flower pots.

Decoration
Either type of roots can be planted in a flower pot, which gives them a different texture.
