Dieffenbachia Seguine 'Tropic Snow'. Everything about the dumb cane, or dieffenbachia, is dramatic. Native to the tropics of Central and South America, it has huge variegated leaves. Even the way it grows is showy, new leaves curling up from the central stem before they unfurl. Price exclude basket. Diffenbachia likes a good amount of light throughout the day, but ideally not direct sunlight. 2-3 times a week. Water sparingly, making the potting mixture barely moist and allowing the top third to dry out before watering again.
