Crassula muscosa
Crassula muscosa (also known as Rattail crassula) - is a succulent plant native to South Africa and Namibia, belonging to the family of Crassulaceae and to the genus Crassula. It has very small, light green leaves that are densely packed around a thin stem, and the arrangement of the leaves around the stems gives them a square shape. It grows as an intricate bush with very small yellow-green flowers, with a maximum height of 15–20 cm. It loves environments with a moderate degree of humidity, in which the soil is well drained and composed of fertile soil and sand.
As the plant gets older, it drops many of those small little leaves and can spread to an area covering meters, which is ideal for any open sunny spots in the garden. (I have found that it actually also grows quite well in the shade.)
In bright sunlight
In a shady spot
Also known as the Watch Chain Plant, if planting it indoors, place in a room that gets a lot of sunlight, such as near a north-facing window. Best color maintained with a little shade, even
on the coast.
