About Dieffenbachia
Dieffenbachia is a genus of around 50 species from the tropical forests of Central and South America. The common name "dumb cane" refers to the calcium oxalate crystals in the sap, which can cause temporary swelling and speechlessness if ingested. Despite this, they have been popular houseplants for over a century, valued for their bold, variegated foliage and tolerance of indoor conditions.
Varieties in Our Collection
Dieffenbachia Camilla is one of the most popular cultivars, with creamy-white centres and green margins. Dieffenbachia Reflector features dramatic dark green leaves with lighter green camouflage patterning. Dieffenbachia compacta stays smaller and bushier, making it ideal for desks and shelves. Green Magic offers deep green leaves with a prominent white midrib.
Light and Positioning
Dieffenbachia thrive in bright, indirect light but adapt well to moderate shade. Direct sunlight can scorch the leaves, while very low light may cause the variegation to fade. They make excellent companions for other shade-tolerant species from our low light plants collection and pair well with the patterned foliage of Calathea and Aglaonema plants.
Watering and Care
Water when the top few centimetres of soil feel dry. Dieffenbachia prefer consistently moist (not soggy) soil and benefit from regular misting or placement in a more humid room. Feed monthly during spring and summer with a balanced liquid fertiliser. They are relatively easy-going and feature alongside other beginner-friendly plants in our easy care collection.
Safety and Handling
Dieffenbachia sap contains calcium oxalate crystals that can irritate skin and are toxic if ingested. Wear gloves when pruning and keep these plants out of reach of children and pets. For pet-safe alternatives with similar bold foliage, browse our pet-friendly plants collection.
