A firefly bush is a decorative plant that spawns firefly particles around it when exposed to darkness.
Obtaining[edit | edit source]
Breaking[edit | edit source]
Firefly bushes can be broken instantly with any item or by hand. It always drops itself upon destruction[1].
Block | ![]() | |
---|---|---|
Hardness | 0 | |
Breaking time (secs) | ||
Default | 0.05 |
- drops nothing
- drops something other than the block itself
- drops the block itself
- italicized can be instant mined
Firefly bushes are also removed and drop as an item if:
- its attachment block is moved, removed, or destroyed.
- water or lava flows into its space.
- a piston tries to push it or moves a block into its space.
- it is placed on a mud block, and that mud block converts to clay.
Natural generation[edit | edit source]
Firefly bushes generate in the form of random patches, on grass blocks near water in most Overworld biomes. They also can generate on mud blocks near water in mangrove swamps.
In swamps, firefly bushes can generate anywhere, instead of being limited to near water.
Firefly bushes in Bedrock Edition have fewer exceptions for which biomes they can generate in, but since grass does not naturally generate in all Overworld biomes and the list still excludes badlands, eroded badlands and wooded badlands, they are actually found in less places than in Java Edition.
Post-generation[edit | edit source]
When bone meal is applied to a firefly bush, the bush spreads to neighboring blocks.
Usage[edit | edit source]

A firefly bush emits firefly particles if the internal light level at its position is 13 or lower. A firefly bush can produce particles even if it is covered by blocks. Firefly particles glow in the dark, but do not actually light up their surroundings. Firefly particles move erratically and collide with solid blocks.
On each tick, a firefly bush has a 70% chance of emitting a new firefly particle in an air block up to 5 blocks above the bush and horizontally up to 5 blocks away in Java Edition, or up to 10 blocks away in Bedrock Edition. A firefly particle lasts between 36 game ticks (1.8 seconds) and 180 game ticks (9 seconds), fading from transparency into an opaque pale yellow color, and back into transparency before disappearing.
The pulsating "fireflies" on the bush itself remain at maximum brightness regardless of the surrounding light level. This affects placed firefly bushes, but the item form of firefly bushes still appear at the surrounding brightness level.[2]
In Bedrock Edition, firefly bushes can be snowlogged. When snowlogged, a firefly bush doesn't emit particles nor ambient sounds.
Composting[edit | edit source]
Placing a firefly bush into a composter has a 30% chance of raising the compost level by 1. A stack of firefly bushes drops an average of 2.74 bone meal.
Ambient sounds[edit | edit source]
At night (between 12600 and 23400 ticks), a firefly bush emits firefly buzzing sounds if no collidable blocks (excluding leaves) are placed above it. A firefly bush may still produce firefly particles in a dark cave or an unlit space, without the bush emitting ambient sounds if it is daytime.
