A dark oak tree is a variant of the Oak tree with a thick trunk. They are found in the dark forest biome.

Structure
Dark Oak trees generate with thick 2×2, and generate dirt blocks under their trunk if generated on a steep cliff. Dark oak trees nearly always generate with irregular logs connected to the trunk – these represent large branches.

Growing these trees requires four dark oak saplings arranged in a 2×2 grid; they do not grow if planted individually. Dark oak trees grow at a much faster rate than most other trees. They require a 3×3 column of unobstructed space at least 7 blocks above the sapling to grow (8 blocks including the sapling itself). This column is centered on the northwestern sapling. Additionally, dark oak trees require 5×5 layers without obstruction for the top 3 layers of its final height. No horizontal clearance is needed at the base of the tree (saplings planted in a 2×2 hole 1 block deep still grow).

Dark oak trees with trunks consisting of 1×1 dark oak logs, instead of 2×2, can be found in two types of rooms in woodland mansions: the tree chopping room, and the nature room. These are not generated elsewhere in the world, and cannot be grown from saplings.

Dying trees
$$, dark oak trees can generate as a dying tree. Dying dark oak trees generate naturally, and can be grown out of normal saplings. A dying dark oak tree has the standard growth pattern of any other tree, however, all exposed logs in the main trunk are covered with vines.

Trivia

 * Large jungle trees and dark oak trees generate with dirt under them if they generate partly or wholly over air or water blocks.
