Shiverthorn

Shiverthorn is a Herb which appears as a stocky blue plant with white branches. It grows only on snow, and only on the surface where there are no back walls. 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 or Snow Blocks. These are merely rumours. In actuality, the Shiverthorn's behaviour can be likened to that of the Blinkroot, in that the Shiverthorn will grow, and then randomly bloom on and off, albeit with considerably longer intervals compared to the Blinkroot. As with all herbs, 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.
