Fire Lily

Note to moderators: if this post is too similar to another or breaks any rules, please link that post or tell me which rules so I can comment or revise accordingly.  Thanks!

Deep in the ground, among the lava and monsters, you can find many treasures, from diamonds to lapis lazuli.  The Nether, too, holds treasures too, with gold scattered among the charred rock.  This post concerns a new treasure found in lava-filled areas: the Fire Lily.

Fire Lilies can spawn underground from altitudes 20-7.  They spawn near lava, where they can grow on dirt, coarse dirt, gravel, obsidian, stone, and magma blocks.  They provide a light level of 15.  They can also grow in the Nether wastes and basalt deltas, at any altitude under 130, but more commonly near lava.  They can grow on any block in the Nether other than those that spawn in generated structures.  Rarely, they spawn in flowerpots in Bastion Remnants.  Fire Lilies are also sold by the wandering trader for 7 emeralds as a final trade.

When picked up, they have a unique item sprite and a cool function.

A Fire Lily, when held, acts as a portable torch, providing light around the player when held in the hand or offhand.  They can be placed in flowerpots and on any block they'll naturally generate on.

They could also be of use in potions, but I'm not sure what for.  A potion that makes all attacks deal fire damage?
