Aloe castelloniae is an unusual, sprawling, cliff-dwelling aloe, native to south-west Madagascar. They form large colonies and clusters of rosettes with bright red/orange flowers when provided enough sunlight and adequate care.
If placing outside during the warm summer months, they can tolerate full sun to partial shade.
Like most cacti, they are slow growing and prefer bright, direct sunlight (6+ hours daily) and watering only when soil is completely dry. Pot in a well-draining cactus/succulent soil mix.
