See the plants native habitat above for ideas on how it can be encouraged to grow. This species is a lichen, which is actually a symbiotic association of two different species, one an algae and the other a fungus. It is very slow-growing. This plant is often used in commercially produced disinfectants.
The only way of reproducing this plant is vegetatively. Almost any part of the plant can be used to produce a new plant, simply separate a portion and place it in its new hom.
A jelly is made by boiling the whole plant. It is nutritious and medicinal. Rather bitter, it requires leaching, which can be done by changing the cooking water once or twice during the cooking process. The dried and powdered plant can be mixed with wheat and used in making bread. It is very bitter and the process required to leach it is far too time-consuming and tedious to be countenanced
