Dieffenbachia 'Compacta' (Dieffenbachia maculata), popularly called Dumb Cane, is a bushy, slow-growing evergreen foliage plant grown for its large, oval leaves splashed with cream, white and pale green markings. Its compact, dense habit makes it a favourite tabletop and floor plant for Indian living rooms, offices and reception areas.
It thrives in the warm, humid conditions found across much of India and tolerates the moderate light of indoor spaces, making it one of the most forgiving decorative houseplants. With minimal care it stays lush and attractive year-round.
All parts contain calcium oxalate crystals, so it should be placed out of reach of children and pets, but as an air-freshening, low-maintenance accent plant it is hard to beat.

| Fertilizer |
Feed a balanced liquid houseplant fertilizer monthly during spring and monsoon growth; pause in winter. |
| Pruning |
Remove yellow or damaged lower leaves; pinch back to keep the plant bushy. Wear gloves as sap is irritant. |

Stem cuttings or cane sections rooted in water or moist soil; also by basal offsets. |
| Pests & problems |

Uses

- Helps freshen indoor air as part of a houseplant collection
- Adds tropical, variegated greenery to shaded balconies and verandas
Growing tips
- Place near an east or north window with bright, filtered light; rotate the pot occasionally for even growth.
- During the hot, dry pre-monsoon months, mist leaves and keep humidity up; reduce watering in winter to prevent root rot.
- Feed monthly through the active growth period (spring to monsoon) and pause feeding in cooler months.
- Wipe dust off the broad leaves regularly to keep them glossy and able to breathe.
- Always wear gloves when pruning or repotting as the sap is a skin and mouth irritant.
