Cold store until planted (up to 3 years).

The seed is harvested as soon as the fruits are bright red. Caution: berry juice may irritate skin. Found in rich, moist deciduous woods and flood plains. Full shade. Unusual green/maroon flower (spathe and spadix). Height to 2 feet. Red berries ripen in fall and are showy.
