This species, as the others of the genus Adromischus, can be found in South Africa, only around Laingsburg and Whitehill (Cape Province) where it grows on exposed rocky slopes.
It’s a perennial with fibrous roots and little branched stems up to 20 centimeters long. Leaves are light green, pointed (mucronated), flattened, vaguely drop-shaped. They can be also rhombic. The flowering period of Adromischus liebenbergii is in December and January, and the inflorescence is the spike-like thyrse typical of Adromischus genus, it is generally 20 centimeters long. Flowers are pale green with sometimes shades of red, and they are tiny (1 centimeter long).
As the other species of the genus Adromischus, A.liebenbergii needs a well-drained soil, so you shouldn’t water it very often (once a month in winter, twice a month in spring and summer). It’s better to keep it indoor, to protect it from the winter rains. The survival temperature of this plant is around 5 ºC. It bears better low temperatures if the soil is kept dry. If it turns too much dry, leaves can fall.
Leaf cutting is the best method of propagation, considering that, also in its natural environment, new individuals are often generated from falling leaves. It consists in cutting a leaf with a sharp knife, putting it in the soil, and waiting until it has put new roots.
