The Fireblossom is a small, magma-colored flower that grows on Ash Blocks in the Underworld. They will only bloom at sunset (between 3:45pm and 7:30pm). Fireblossom will grow wherever Ash Blocks are placed, not just in the Underworld. However, the blooming condition is the same regardless. The player can also plant Fireblossom in Clay Pots, or Planter Boxes from seeds, which are obtained from blooming Fireblossom plants.
