Description Star Window Plant Care Guide FAQ/Common Issues Haworthia cuspidata - Star Window Plant is a compact succulent native to the Eastern Cape of South Africa, where it grows in rocky, semi-arid terrain beneath shrubs and overhanging rocks. Part of the Haworthia genus in the Asphodelaceae family, it grows indoors as a desk plant and bedroom companion for anyone seeking a drought-tolerant species with genuine staying power. It forms tidy, symmetrical rosettes of fleshy, triangular leaves tipped with translucent "windows" that filter light down into the plant's interior. The leaves are bright green with subtle striping, and the clumping growth habit means one pot naturally fills out into a full, layered display over time. Star Window Plant stays compact, typically reaching 3-5 inches in diameter per rosette, making it suited to tight shelving and small spaces. It produces small pale flowers on spikes, typically appearing in spring when conditions are right. A slight nighttime temperature drop in autumn can encourage blooming. It is non-toxic and safe for cats and dogs. You can leave it up to ten days without water. Move it outside in summer in a sheltered, bright spot, but cover it from rain and bring it indoors before temperatures drop. Propagate it by gently removing the offsets that form around the base of the mother rosette, allowing each offset to callous for a day before planting in fresh succulent mix. Haworthia cuspidata - Star Window Plant grows well in medium or bright indirect light and grows well under standard office LEDs. Water it every 2-3 weeks, allowing the soil to dry completely between waterings. Star Window Plant does best in a fast-draining cactus and succulent mix amended with extra perlite. It prefers temperatures between 65-85°F and should be protected from frost below 30°F. Star Window Plant is a slow to moderate grower that needs only a light balanced feed once in spring and once in summer. It is hardy in USDA zones 9-11, tolerating brief dips to around 25-30°F before frost damage becomes a risk. It grows outdoors year-round in Florida, Texas, California, Arizona, Hawaii, Louisiana, Georgia, South Carolina, Alabama, Mississippi, and Nevada. Coastal areas of Oregon and parts of New Mexico and Arkansas within zone 9 microclimates can also support it through mild winters. Q: How often should I water Haworthia cuspidata - Star Window Plant?
