Cactus Flower is a renewable pink flower introduced in Minecraft Java Edition 1.21.5 and Bedrock Edition 1.21.70. The flower generates naturally on top of cacti in desert and badlands biomes, where 25% of wild cacti already carry one. A player-planted cactus one or two blocks tall has a 10% chance to sprout the flower instead of growing taller, and a three-block cactus raises that chance to 25%. Cactus Flower breaks instantly by hand, has a hardness of 0 and a blast resistance of 0, and stacks to 64.

Players use the bloom mainly as a Pink Dye ingredient: one Cactus Flower yields one Pink Dye on any crafting grid, matching the 1:1 dye yield of other single-flower recipes. Bees pollinate the flower to produce honey and can be fed the bloom to enter love mode and breed. Composters gain one level with a 30% chance per flower. The bloom cannot be placed in a flower pot and stops the cactus beneath it from growing taller, so desert builders often leave blooming cacti standing as a decorative hedge line.
