A Large Fern is a two-block-tall variant of the Fern that naturally generates in taiga, snowy taiga, and old growth taiga biomes, as well as around taiga village houses. It can be obtained by using shears, which causes it to drop two ferns instead of itself.
Breaking a large fern normally has a 12.5% chance to drop wheat seeds, with the Fortune enchantment increasing the number of seeds. Placing a block on top of a large fern destroys it without dropping seeds. Large ferns can also generate in taiga village chests and can be created by using bone meal on a regular fern. They can be placed in composters, with a 65% chance to increase the compost level.
