Shiverthorn

Shiverthorn is a Herb which appears as a stocky blue plant with white branches. It grows naturally only on snow. It can be cut with virtually any weapon or tool, and can be planted in Clay Pots using Shiverthorn Seeds.

Shiverthorn does not require a blizzard to bloom, nor does it require any kind of falling snow, Snow Blocks or background walls removed (it does grow with background walls on blocks). These are merely rumors. While previously it was believed that the Shiverthorn acted as a slower Blinkroot, it has become abundantly clear that it simply has a long growth cycle. Shiverthorn is the only flower to stay blooming at all times once it has reached the blooming stage, without need for any kind of catalyst and without any chance to stop blooming, as Blinkroot or other time/event flowers would.

As with all herb flowers, they will drop 1-3 seeds if cut while in bloom. Fully grown and blooming Shiverthorn plants will have a crown of jagged, light blue petals on top and will additionally give off light and particle effects. As there is a lack of any external requirements for the Shiverthorn to bloom, indoor growth is entirely possible.
