Many species of Huernia have been moved to this genus from their closely related cousins, the Stapelia.
Over the several centuries since their discovery by missionaries in South Africa, these interesting plants have been grown as odd houseplants or in conservatories and greenhouses, but originally the villagers in South Africa used them as a food plant, boiled like a vegetable.
Huernia resemble Stapelia by producing the distinctly scented flowers that lead to the name of Carrion Flower.
The smell and the dark red of some types resemble the blood or flesh of dead animals, which attracts the flies that pollinate them.
The green stems have adapted to perform the same function as leaves, with less likelihood of damage from excessive heat and drought.
The green colour indicates that they can photosynthesize, making sugar from the presence of light.
They can exist in extremely difficult situations; if a long dry period persists, the stems simply shrivel gradually until the next rainfall.
The sharp looking ‘thorns’ are all show – they are soft, and can’t harm your skin.
In time, they’ll bloom, usually after a drought ends, and they can again receive water.
Let this little characteristic allow you to promote blooming when you want it, not when the plant decides it’s time.
Honestly, the smell of some of the different species is pretty overwhelming, and you will be happier if they perform this duty out in the fresh air.
For summer, Huernia and Stapelia both do best in some type of lath house, or at least dappled shade.
Even though they originate in extremely hot areas of the world, the fact that they aren’t frost hardy makes it difficult to provide enough light in the winter time to keep them toughened up from too much light.
I find for the winter, 12 hours under fluorescent grow lights is perfect, as they come from around the equator. This will give them a similar photoperiod to their native lands.
As succulents, they require well drained soil, and do quite well without much in the way of fertilizer.
To promote bloom without too much excessive growth you can fertilize with a weak solution of 5-10-10 fertilizer (the first number is Nitrogen, so any fertilizer with lower numbers there will be best for succulents).
For an organic choice, simply sprinkle some worm castings on the top of the soil, which act as a slow release fertilizer whenever you water.
