Shiverthorn Seeds are a type of seed that can be obtained from harvesting Shiverthorns while they are blooming or using the Staff of Regrowth on a naturally grown Shiverthorns while they are fully grown. Shiverthorn will always bloom after a period of growth, and unlike other herbs, remains in-bloom permanently thereafter. Blooming Shiverthorn emits a glowing particle effect. Each plant drops 1–3 Shiverthorn Seeds when harvested while blooming.
Shiverthorn Seeds can be placed on Snow Blocks and any type of Ice Blocks, empty Clay Pots, or any types of Planter Boxes, even inside water or honey, and will grow into harvestable Shiverthorns. They will grow anywhere, not just in the Snow biome, but will only yield seeds when blooming.
