bright indirect light (3-6 feet from a south or west window, or right next to an east window. Under a grow light, 6-10 inches away works well) is ideal. It tolerates lower light better than most succulents thanks to its leaf windows, but avoid harsh midday sun which scorches leaves.Light
Use the soak-and-dry method: water thoroughly (water until it drains out the bottom. Empty the saucer after 30 minutes so the roots are not sitting in water), then wait until the soil is fully dry before watering again. Water every 2-3 weeks during the growing season and cut back significantly in summer when the plant goes semi-dormant.Water
Tolerates typical household humidity (30-50%). Good air circulation matters more than hitting a specific humidity target.Humidity
Thrives at 60-80°F (15-27°C). Can handle brief dips to around 30°F (-1°C) but prefers to stay above 50°F. Hardy in USDA zones 10a-11b.Temperature

Star Window Plant

Haworthia cuspidata

Easy

Haworthia cuspidata is a compact, rosette-forming succulent with lime-green to grey-green wedge-shaped leaves tipped with translucent 'windows' that channel light into the plant's interior. It is likely a natural hybrid of H. retusa and H. cymbiformis, and offsets freely to form cheerful little clusters. You get a lot of personality for a very small footprint, and it is one of the most forgiving succulents you can bring indoors.

Fun Facts

The translucent leaf tips act as built-in solar panels: they funnel light down into the plant's interior so it can photosynthesize even when largely buried underground in its native South African habitat.

Pet Safety

Pet safe

Non-toxic to cats, dogs, and humans. One of the safer succulents for pet-friendly homes.
