Plant size: 10.5 cm x18cm (approx)
The Senecio Haworthii ‘mont Blanc’ also known as the cocoon plant, is a small shrub-like specimen, growing upright to 30 cm in its native South African conditions. A perennial plant, this succulent has most appealing white foliage, making it a must-have. Pet safe.
Care: Water and let it dry out completely before watering again. Hates being overwatered so underwater if anything. 
Humidity: Low, likes a dry spot
Light: Like most succulents, the Senecio haworthii will do best in bright sunlight, such as by a window, though they can also get by in slightly shadier conditions (of course, with lower light the plant will also need to be watered less frequently and will likely grow at a slower rate).
