How to care for your Windowpane Plant

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

Haworthia cooperi, charmingly known as the Windowpane Plant, is a captivating succulent that forms tight rosettes of soft, gelatinous leaves. The most striking feature is the translucent, window-like tips of its leaves, which allow sunlight to reach chlorophyll deeper within the plant. This adaptation is common in plants growing semi-buried in their natural habitat. It readily offsets, creating attractive clumps, and is perfect for small containers or terrariums, thriving in bright, indirect light.
