Huernia macrocarpa are also known as Stapila macrocarpa, an easy care succulent that produces deep red blooms throughout the year. They prefer bright light and can tolerate direct sun, just avoid harsh midday sun (morning and afternoon sun it okay) They can also get purple-ish markings when sun-stressed.
 
They are planted in our Wildvine Cacti & Succulent blend, so won't need repotting until next summer. Water thouroughly when mix is completly dry, these plants are drought tolerant so don't mind drying out completly between waterings. Less in winter.
