How to care for your Star Windowpane Plant

Everything you need to keep your Star Windowpane Plant healthy: watering, light, humidity, feeding, repotting and pruning.

Haworthia retusa, often called the Star Windowpane Plant, is a fascinating succulent prized for its distinctively shaped, plump leaves. These leaves are typically triangular and end in a flattened, translucent tip, allowing light to penetrate the plant's interior, an adaptation to its natural habitat where it often grows partially buried. The rosettes have a somewhat 'retuse' or blunted appearance. It's an easy-care plant that thrives in bright, indirect light and well-draining soil, perfect for indoor enthusiasts.
