Features Documentation - minecraft:tree_feature
minecraft:tree_feature places a tree in the world. A tree consists of a column that is anchored to a base block with set parameters for what it can be placed on and canopy that extends from the column. The trunk height can be randomized with a min and max value, as well as the canopy offset.
