Appearance

As mentioned above, the most distinguishing feature of the star cactus succulent is its star-shaped markings.

Care Requirements

The star cactus succulent is a relatively low-maintenance plant that requires minimal care. Here are some tips for keeping your star cactus succulent healthy and thriving:

Soil

The star cactus succulent prefers well-draining soil that is slightly acidic in nature. A mix of potting soil, perlite, and sand is ideal for this plant.
