Heartblossom

Heartblossoms, named for its deep red color, are delicate, nectar-producing flowers that grow close to the ground, and always in pairs. If one blossom is taken, the other flower begins to wilt immediately and dies soon after. It is considered very unlucky to disturb a Heartblossom without blessing it first.

Fungal Moths prefer to feed on Heartblossom nectar.
