Blazebloom

Blazebloom is a type of plant found only in the underworld growing randomly all over the ground. Once fully mature they drop a blazebloom flower and a few seeds. The Blazebloom is a key ingredient to crafting an Obsidian Potion.

Farming
You can grow blazebloom by planting Blazebloom Seeds on the ground anywhere in the underworld, they can NOT be planted on tilled soil outside the underworld. However, if you dig some infernal dirt and put the infernal dirt down in a hole you dig in any level, you can plant and grow the blazebloom on the infernal dirt you placed, this way you can grow blazebloom in any level.
