Dieffenbachia seguine is a tropical aroid plant with a vertical, bamboo-like growth habit. It features large green leaves often adorned with striking white variegation patterns. Mature plants can reach 10 feet tall with trunk widths up to 3 feet, though houseplant specimens typically remain smaller. Its toxic sap contains calcium oxalate crystals that can cause severe reactions if ingested, and it produces characteristic aroid inflorescences with a white spathe surrounding a spadix.
