WHERE & HOW TO FARM
Where to farm
Fireblossom grows on Underworld ash; Shiverthorn grows on snow or ice. Maintain each in a separate Planter Box.
Collect Fireblossom from Underworld ash and Shiverthorn from snow or ice, then plant each in its own Planter Box. Fireblossom blooms at sunset or in lava; Shiverthorn blooms after growing for a while. Wait for the appropriate state when collecting seeds, then harvest for potion use while retaining planting stock. The home garden keeps later harvests accessible, though you must visit each region for the starter supply. Organize the rows so each herb can be harvested when ready.
