Putrid Gigantea is a plant native to the Shivering Isles, specifically in Dementia where it grows in abundance and gives Congealed Putrescence. It is an odd looking plant —short, mainly russet in color, and resembling a cone with an especially bloated base. There are some people on the Isles that appear to consume Congealed Putrescence as food, despite its name and appearance. Putrid Gigantea also appears on the island with the Strange Door.
