Dieffenbachia 'Tropic Snow' (a selection of Dieffenbachia amoena), commonly called Dumb Cane, is a striking evergreen foliage plant grown for its large, broad leaves heavily marked with creamy-white and pale-green variegation along the midrib. It forms an upright, cane-like clump and is one of the most reliable indoor plants for the warm, humid conditions found across much of India.
Tolerant of low to moderate indoor light, it thrives in bright rooms with filtered light and quickly becomes a lush statement plant. It is widely used to green up living rooms, lobbies and office interiors. Note that all parts contain irritant sap, so it should be kept away from young children and pets.

| Soil / mix |
Rich, well-draining potting mix of garden soil, compost and coco-peat or sand; pH slightly acidic to neutral. |
