Dieffenbachia, commonly known as dumb cane, is a popular tropical houseplant prized for its large, striking, variegated leaves. These robust plants feature broad, oval foliage with distinctive patterns of green, cream, and yellow markings that vary dramatically between varieties. Native to Central and South America, Dieffenbachia are relatively easy-care plants that thrive in bright, indirect light and prefer consistently moist but well-draining soil.
