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 blooms during a blizzard, and will drop 1-3 seeds if cut at that time. Fully grown and blooming Shiverthorn plants will have a crown of white branches on top. It does not need to be snowing directly on the plant for it to bloom, so growing them indoors is possible.
