Dieffenbachia (Dumb Cane): Lush, Patterned Foliage for Low Light

Dieffenbachia: Bold Leaves, Easy Care, Serious Toxicity

Native from Mexico to Argentina, dieffenbachia (dumb cane) offers large, broad, oblong leaves splashed with cream, yellow, or white patterns. Varieties range from compact tabletop plants to 5–6 foot floor specimens. Fast-growing and tolerant of low light, they become top-heavy without regular pruning.

Care Basics

Medium to low indirect light; water when the top inch of soil dries. Average humidity and temperatures 65–75°F suffice. Repot every 2–3 years; stake tall canes.

Critical Safety Note

The common name “dumb cane” comes from the sap’s ability to cause temporary speechlessness and severe swelling if chewed. All parts are highly toxic due to calcium oxalate crystals. Keep well away from children and pets; wash skin immediately after contact.
