The Moonflower

The Moonflower is a new flower type which can be crafted into dark gray dye or with glowstone dust to create Magic Dust which could be used if we get a magic-themed update. 

How to get it.

I suggest either you need to go to the End Dimension and use a fertilizer of some kind (e.g. bonemeal or maybe traded from wandering trader) to grow a Moonflower on endstone blocks or you can find it in End City loot chests. Or maybe even a new boss of some kind that whenever it kills passive mobs it spawns the moonflower (e.g. Like the wither-rose in the 1.14 update)

I know we have already gotten 2 new types of flowers in the Village and Pillage Update but I think that Mojang can implement this into many different scenarios and ideas they already have!
