About Crassula muscosa L.
Crassula muscosa L. produces very small, light green leaves that are densely arranged around a thin stem. The pattern of leaf growth around its stems creates a square shape. This plant grows as an intricate bush, bears very small yellow-green flowers, and reaches a maximum height of 15–20 cm (6–8 in). Crassula muscosa is native to South Africa, where it occurs in the Cape Provinces, the Free State, and the Northern Provinces, as well as Namibia. It grows in habitats with moderate humidity, where the soil is well drained and made up of fertile soil mixed with sand. In cold seasons, Crassula muscosa tolerates temperature drops to a minimum of 6–8°C, and requires very little water. In summer, it needs much more water, and should not be exposed to full sun, because it is damaged by excessive sunlight. When these growing requirements are not met, the plant begins to dry out and stiffen, a change that generally starts at the base of the stem and progresses toward the tips. This species is an invasive plant, and can be easily propagated from stem cuttings. If cuttings are kept in an environment with a stable temperature of 20–21°C, plus adequate humidity and brightness, the cuttings will root and grow rapidly.
