Nightlock Berries

Nightlock is a wild plant with extremely poisonous berries. Katniss first heard about this plant from her father, who cautioned her that anyone who ate nightlock would be dead before the berries even reached their stomach. Although this phrasing may be an exaggeration, the plant's effects are indisputable: Foxface indeed died very quickly after consuming nightlock. The only known sources for these deadly berries are the land around Districts 12 and 13, though they were also featured in the arena of the 74th Hunger Games.
