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.
