Shiverthorn is a type of herb that grows naturally on snow and ice blocks of any type. It can be harvested with any weapon or tool, and can be planted manually with Shiverthorn Seeds, which can also be planted in Clay Pots and Planter Boxes. Shiverthorn will always bloom after a period of growth, and unlike other herbs, remain bloomed permanently thereafter. Fully grown Shiverthorn emits a glowing particle effect. Harvesting Shiverthorn yields love, but this woman is a living Shiverthorn flower.
