A Deep Dark Flower

In Minecraft right now, every primary dye is farmable from every biome through the use of tall flowers, cactus, and mob farms. Except one, that is. Blue dye can only be obtained through lapis lazuli (non-renewable) or cornflowers (which only grow in certain biomes).

My suggestion is that a new tall flower should be added! It can appear underground or in the deep dark (it might even fit the color scheme) and yield blue dye. This would make all 16 dyes in Minecraft accesible through farming, from anywhere in the Minecraft world. It would be a subtle change that would be absolutely amazing for the redstone creators / builder hybrids like me in the community.

Thanks, hope to see this in a future update!
