Greatwood Sapling (Thaumcraft 5)

The Greatwood Sapling is a sapling added by Thaumcraft 5, which grows into a Greatwood Tree. The Greatwood Tree is harvested to gain Greatwood Logs (and possibly Greatwood Leaves).

Every 1/8 Greatwood Trees spawned naturally in the world is haunted by spiders; the Greatwood Tree will be covered with Cobwebs, and a Cave Spider Monster Spawner will be underneath one of the bottom Greatwood Logs. However, under that Spawner is a random Dungeon Chest.

Trivia

 * Thaumcraft 5 Greatwood Trees are larger than any other version of Thaumcraft.
