Light Flowers are plants that serve as a sources of light that can normally be found in Caves and Ruins. They are generated all over the caves but mostly spawn in Cave Swamp, and Wilds in the Ruins. The Light Bulb(s) can be picked from Light Flowers, and they can be used in the crafting and refueling of a Lantern, and in the refueling of a Miner Hat. There are three types of light flowers, each yielding a different amount of Light Bulbs.
The Light Flower is a small light source, capable of protecting the player from Charlie's attacks. It ceases to act as a light source once picked. The double- and triple-bulb plants yield 2 and 3 bulbs respectively when picked. It takes 3 days for a flower with one bulb to regrow, 4–5 days for a two-bulbed flower, and 6 days to spawn a three-bulbed flower.
Light Flowers cannot be relocated elsewhere with a shovel, and are thus limited to their natural habitat in Caves and Ruins.
If a picked Light Bulb is placed on the ground, it will generate a small light source, but some creatures like Pigs and Gobblers will eat them, the former resulting in Manure.
In Don't Starve Together the Light Flowers have a dormant stage, which is indicated by a clock that only appears when in the light. In their dormant stage, they do not produce light.
- Light Flowers were added in the Underground update.
