Infobox
Purple Charnia is a variety of underwater frond found in End Lakes and Geysers.
Obtaining
All varieties of Charnia naturally generate at the bottoms of End Lakes (including Megalakes), Sulfur Lakes and Geysers.
They can also be grown by using Bone Meal underwater in The End,
though that can be disabled in the Lighter End config, accessed either through
ModMenu or by editing config/lighterend.yaml
in your Minecraft folder and setting the line:
bonemealing_underwater_in_the_end_produces_end_vegetation: falseUsage
