See the plants native habitat above for ideas on how it can be encouraged to grow[PFAF]. 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[2]. This plant is often used in commercially produced disinfectants[3].
