Dieffenbachia seguine (dee-fen-BAH-kee-ah seg-WE-neh)
Dieffenbachia is an erect, broadleaf evergreen perennial in the Araceae family that is native to Central and South America. The large, shiny, green leaves are variegated in a variety of patterns of patches or blotches in colors of cream, white, or yellow. It grows from 3 to 8 feet tall and 2 to 3 feet wide and is scarcely branched. It is a popular houseplant and is grown for its ornamental foliage. It rarely develops flowers or fruits as a houseplant. The genus name, Dieffenbachia, is in honor of J.F. Dieffenbach, who was in charge of the royal palace gardens in Vienna in the 1830s. Plants formerly designed as D. amoena , D. maculata , and D. picta are now placed in D. seguine. The common name, dumbcane, refers to the numbing and paralyzing effects of the sap of this plant on the vocal cords of humans and pets if it is ingested. This plant prefers loose, fertile, high organic soil and indirect light, moderate temperatures, and high humidity. Water the plant thoroughly and allow the top 1-inch surface of the soil to dry completely before watering the plant again. This will help prevent root rot. It needs to be protected from cold drafts and direct sunlight. Propagate by division or stem/root cuttings. Although Dieffenbachia is grown as a houseplant, it can be toxic for pets and children. Be alert for toddlers and pets that might eat or chew on the leaves. Always make sure to wash your hands after handling this plant and keep your hands away from your eyes and mouth. This plant has an exotic appeal and has wonderfully shaped rich green leaves with brush strokes of cream, yellow, and white which enhance the shape of the leaves. This plant will stand out and brighten the dark corners of your home.
