Aglonema Silver Bay A very adaptable plant, it tolerates low light and dry air better than most other house plants. One thing it doesn’t like is cold air. Its large, pointed, dark-green leaves are 6-10 inches (15-25 cm) long, 3 inches (7.5 cm) wide, and heavily marbled with white, cream, or silver and white. Small flowers may appear in summer, followed by red berries. The berries and sap of this plant are poisonous.
