Dieffenbachia — 15 species

Dieffenbachia — commonly called Dumb Cane — is a bold tropical foliage plant from the Araceae family, prized for its large, patterned leaves in shades of green, cream, and white. It thrives in bright to moderate indirect light and tolerates lower light, though leaf patterns fade in dim conditions. Water when the top two inches of soil dry out, roughly every seven to ten days, and avoid waterlogging. All Dieffenbachia species are toxic to cats and dogs; the insoluble calcium oxalates cause intense oral irritation, drooling, and difficulty swallowing.
