Aglaonema Silver Bay (Aglaonema commutatum ‘Silver Bay’) is a hybrid cultivar in the aroid (Araceae) family. It is also referred to as Silver Bay Chinese evergreen and poison dart plant. It’s an evergreen perennial that can grow up to 4 feet tall and wide.
Aglaonema species originated in the tropical and subtropical areas of Asia and New Guinea. Aglaonema Silver Bay was hybridized by Dr. Jake Henny at the University of Florida in 1992. He crossed Aglaonema ‘Manila Whirl’ with Aglaonema nitidum ‘Ernesto’s Favorite’ to create Silver Bay Aglaonema.
He began hybridizing Aglaonema houseplants because they tolerate low humidity and light conditions. The leaves have large silvery-gray areas of variegation up the center of the green leaves. The variegation covers about ⅔ of the leaf’s surface area.
