Haworthia retusa - STAR CACTUS
Haworthia are able to tolerate low, indoor light, making them excellent houseplants, even for beginners. Some have firm, tough leaves, while others have softer leaves that contain "leaf windows" with translucent panels. They are particularly easy to grow and rarely affected by common succulent pests and diseases.
