Dieffenbachia Big Ben Variegata is a bold and exotic tropical houseplant belonging to the Araceae family, native to the rainforests of Central and South America. Commonly known as Dumb Cane, this striking cultivar is prized for its large, variegated foliage and easy-care nature, making it a favourite for adding lush greenery to homes and offices.
The broad, oval leaves are a vibrant green, dramatically patterned with creamy-white and light yellow marbling through the centre and along the veins. Each leaf can grow 3040 cm long, creating a full, bushy appearance that gives an instant tropical feel. The Big Ben Variegata variety is particularly valued for its robust growth habit and strong, upright stems that support an impressive canopy of patterned foliage.
With its combination of ornamental foliage and forgiving care needs, Dieffenbachia Big Ben Variegata is ideal for plant enthusiasts seeking a dramatic statement piece that thrives indoors.
Prefers bright, indirect light to maintain vivid variegation. Tolerates moderate light but avoid direct sunlight, which may scorch the leaves.
Water when the top 35 cm of soil feels dry. Keep soil lightly moist but never waterlogged, as Dieffenbachia is prone to root rot. Reduce watering in winter when growth slows.
Temperature: Best kept between 1828C. Avoid draughts and cold below 15C.
Humidity: Prefers moderate to high humidity (5070%). Mist occasionally or place near other plants to maintain moisture around the leaves.
Use a rich, free-draining peat-free houseplant compost mixed with perlite or orchid bark for aeration. Repot every 12 years in spring to refresh soil and encourage growth.
Feed every 46 weeks during spring and summer with a balanced liquid fertiliser. Pause feeding during winter.
Remove yellowing or damaged leaves at the base to promote fresh growth. Rotate the pot occasionally to maintain even shape and prevent leaning towards the light.
A moderately fast-growing plant that can reach 11.2 metres indoors. With regular care, Big Ben Variegata forms a tall, upright plant with lush, overlapping foliage.
Yellowing leaves: Overwatering or poor drainage.
Leaf burn: Exposure to direct sunlight or cold draughts.
Brown edges: Low humidity or inconsistent watering.
Pests: Occasionally spider mites, thrips, or mealybugs.
