The Afrikaans name for “Cocoon Plant” is “Tontelbos”, meaning “tinderbush”. The white coating of the leaves was removed and used as tinder for starting fires.
In its native habitat, it can be found on rocky mountain slopes where it grows to about foot tall (30 cm). Potted up as an indoor plant in my home, it is a mere six inches tall.
The long, tubular, succulent leaves resemble a moth's cocoon (hence the common name) and are covered in fine, silvery-white hairs.
Here are some basic tips on caring for a Cocoon Plant:
Light: Senecio haworthii needs full sun (4-6 hours of sun) or its growth will become leggy.
Water sparingly! These are drought tolerant plants that are used to extremely dry conditions. To avoid overwatering, allow the soil to dry out completely between waterings. When you do water, try to avoid getting water on the leaves. In the winter, the plant's growth slows considerably, so water very sparingly.
Soil: Cocoon Plants like sandy, free-draining soil. They'll rot in damp, soggy soil.
