Crassula humbertii is native to South Africa, where it inhabits arid habitat at a variable altitude range, sprouting among the rocks or in the shade of taller bushes or trees.


Crassula humbertii is a tiny succulent plant, very appreciated among succulent lovers for its extreme adaptability at any cultivation
condition, a distinctive feature that make it suitable also for beginners approaching to the world of ornamental succulents gardening. It
consists in a cluster, actually more of a tuft, of elongated, wiry stems, untidily spreading in all directions, erect but also possibly
falling after some time. It is the perfet planf for a sunny balcony, forming green, falling, abundant tufts like hairs. Its leaves,
fleashy and cylindical or more sausage-like, are more abundant at the top of the stems, forming rosette-alike structures (that aren’t
rosettes for real, but remind them). The colour of the leaves is greyish-green with a darker tinge, somehow brindled by black blurs and
with a reddish hint that becomes more visible on the stem. Leaves are also equipped with short, translucent bristles, that help them to
minimize water loss through evapotranspiration. In spring, this plant will produce little, cute white flowers, solitary and scattered among the plant, sprouting usually at the top of the apical “rosette” on the stems.


Crassula humbertii is not difficult to grow. Here below are our cultivation tips:

The best exposure is in full sun or semi-shade. By the way, intense sunlight enhances the bright red tinges of its leaves, so we advice to put it in a bright spot. Avoid a direct exposure during the hottest hours of summer days. Shade should be only occasional, as plants grown in full shade tend to become more fragile, to loose leaves and turn on a paler colour.
To stay safe, it’s better to keep your Crassula humbertii indoors in Winter or at least to shelter it, if you live in a temperate climate area and you choose to grow it outdoors. Crassulas in general, in fact, should never grow at temperatures below 7 ° C though, in theory, C. humbertii should survive to temperatures down to -5ºC
Water your Crassula humbertii every 2-3 days in Spring and Summer during the growth season. By the way, if you forget, the plant will survive. Wait for the soil to dry up completely before each watering. Watering slightly more frequent in spring may encourage flowering. In autumn and winter, the watering can be reduced up to be completely suspended.
Choose a porous and well drained substrate, fed with plenty of well-rotten compost. An acidic substrate is the ideal for C. humbertii.
Fertilization can be done once the growth season, diluting a product specific for succulents with water at half the doses recommended on the label.
Repot once a year and anytime your Crassula humbertii outgrows its pot. It has, in fact, a rapid growth rate.



Crassula humbertii can be easily propagated through the removal of the offshoots, by removing a lateral one and planting it in a light, well-drained soil. The time required to root is usually a month. Cuttings are easy to realize and thus we recommend this method, instead of sowing, that can be more tough with this plant.


Crassula is the “succulent plant” par excellence: its name comes from the Latin crassus, that means fat. Crassula are undemanding plant, with a high vegetative strength: for this reason, they are often used as air purifiers, having the capacity to remove polluting molecules from the air.
