Dieffenbachia Sterling - Dumb cane

The Dieffenbachia 'Sterling' or Dumb Cane is a timelessly charming indoor houseplant. Its large, strikingly veined with silvery white leaves perfectly combine elegance and exoticism. Stunning in a bright living room or well-lit office, this plant fits beautifully into a modern, zen, or minimalist décor. Place it near an east- or west-facing window or behind a sheer curtain to filter the light. This plant must be watered exclusively with non-calcareous water.

Belonging to the Araceae family, the Dieffenbachia 'Sterling' is a hybrid cultivar developed by the tropical plant breeding programme at the Mid-Florida Research and Education Centre. This plant has an upright habit with vigorous, non-ramified stems bearing soft, elliptical leaves with prominent white veins, measuring between 20 and 30 cm in length. At maturity, it reaches a height of 60 cm to 1m,depending on growing conditions. The growth rate of the Dieffenbachia 'Sterling' is moderate, making it easy to maintain indoors without frequent pruning. Although flowering is rare in indoor cultivation, it takes the form of spadix inflorescences surrounded by a green spathe characteristic of Araceae. The name 'Dieffenbachia' pays homage to the German botanist Joseph Dieffenbach, head gardener at the Vienna Botanical Garden in the 19th century.

Native to the tropical forests of South America, the Dieffenbachia genus thrives in warm, humid environments. Indoors, the Dieffenbachia 'Sterling' prefers bright, indirect light avoiding direct sunlight which may scorch its leaves. Moderate to high ambient humidity is recommended, along with a stable temperature between 18 and 24°C.

Warning - It is important to note that all parts of the plant are toxic if ingested. It is therefore advisable to keep it out of reach of children and pets and to handle the plant with gloves to avoid contact with the sap.

The Dieffenbachia 'Sterling' finds its place in a living room, office, or even a spacious bedroom, provided that it receives sufficient light—but not direct sunlight through a window. With its upright habit and lush foliage, it complements contemporary, zen, tropical, or minimalist styles. Display this fresh yet sophisticated variety in a stylish white ceramic planter for a clean look or in a wicker pot to enhance its natural appeal. Placed near an armchair or in a room corner, it will draw all eyes. To create a harmonious combination, pair the Dieffenbachia 'Sterling' with a 'Camilla' cultivar, whose cream leaves provide a lovely contrast, or with an Aglaonema, which offers broader, brighter foliage.
