Roots

Roots are a non-solid plant-like 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.

Block loot
Roots can be mined instantly with any tool. They drop themselves when broken. Flower pots containing roots drop both the flower pot and roots when broken.

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).

Decoration
Roots are decorative blocks. Roots can be planted in a flower pot, which gives them a different texture.

Compost
Roots can also be used on a composter, with a 65% chance of increasing the level by 1.

Negating fall damage
They can also be used as an alternative to a water bucket when jumping from a high place in the nether and landing on nylium, since they negate fall damage and water cannot be normally placed in the nether.

(Tested this theory, invalid)

It is likely that this theory is for Twisting Vines, as you can escape fall damage by placing one at your feet in the nether.

Trivia

 * Although plant-like, the roots resemble small mushrooms. This is likely the case since all vegetation in the Nether is fungus-based.
