The Cyathea is based upon the extinct species of tree fern Cyathea cranhamii, from the early Cretaceous Period. It is a 4 block tall, solid plant that was added in the 8.0.4 "Morrison Update".
Trivia
- The Cyathea will not be completely destroyed when you destroy the top or middle of it. It will simply remove it and all parts above.
- If you use bone meal on it, it will spawn more fully grown Cyathea next to it.
