Dumb cane is a classic houseplant with large, variegated leaves in patterns of green, cream, and yellow. Its common name comes from the toxic sap that causes temporary speechlessness if ingested. Native to the Caribbean and South America, Dieffenbachia seguine is valued for its lush, tropical foliage and tolerance of low light.
Bright, indirect light; tolerates low light. Keep soil evenly moist but not soggy. High humidity prevents brown tips. Fertilize monthly. Wipe leaves. KEEP AWAY FROM CHILDREN AND PETS—all parts are toxic, causing intense oral irritation and swelling. Wear gloves when pruning.
Many cultivars: 'Camille' (creamy center), 'Tropic Snow' (large leaves), 'Compacta' (dwarf). Propagate by stem cuttings or air layering. It can grow 3-6 feet tall indoors.
