Haworthia Retusa

It forms a tight, clumping rosette of thick, triangular leaves tipped with flattened, translucent “windows” that glow lime green when backlit. Each leaf catches and diffuses light, and individual rosettes stay compact, typically reaching 3 to 5 inches in diameter. Over time, offsets form around the mother plant, building attractive cushion-like clusters.

While not grown primarily for its blooms, plants that experience a slight temperature drop in late winter or spring may produce slender stalks bearing small tubular white flowers. The blooms appear occasionally rather than reliably each year, so they are a pleasant bonus rather than a main feature.

This succulent works well on desks, shelves, and in terrariums, making it a practical bedroom plant or office companion. Move it outside to a sheltered patio spot for summer, keeping it away from rain and harsh afternoon sun. It is non-toxic to cats and dogs. It propagates easily from offsets that form around the base. Simply separate a pup, let it callous for a day or two, then pot it in fresh succulent mix.

Water it every 2 to 3 weeks during the growing season, allowing soil to dry completely between waterings, then reduce to once monthly in winter.

Haworthia Retusa does best in a fast-draining cactus and succulent mix combined with extra perlite for excellent aeration and drainage.

It prefers temperatures between 65 and 80F and must stay above 40F, as it is not frost tolerant.

Haworthia Retusa is a slow grower and needs only a light balanced fertilizer once in spring and once in summer.

It is hardy in USDA zones 911 and tolerates outdoor conditions down to about 25F with protection, though it performs best where winters stay mild. It grows outdoors year-round in California, Arizona, Nevada, Texas, Florida, Hawaii, Louisiana, Georgia, South Carolina, Alabama, and Mississippi, as well as coastal areas of Oregon and parts of North Carolina.

Q: How often should I water Haworthia Retusa?
A: Every 2 to 3 weeks during spring and summer with full soil drying between waterings, then once monthly in fall and winter.

Q: What light conditions work best?
A: Haworthia Retusa adapts well to bright indirect light and medium light conditions, including office LED lights. Rotate it regularly so all sides receive even exposure, and watch for leaf scorching in intense south-facing sun.

Q: Is Haworthia Retusa pet-friendly?
A: Yes, it is non-toxic to cats and dogs and safe for homes with curious animals.

Q: How large does it grow?
A: Haworthia Retusa stays compact, with individual rosettes reaching 3 to 5 inches in diameter and forming attractive clumps over time as offsets develop.

Q: How do I propagate Star Window Plant?
A: Gently separate the offsets that form around the base of the mother plant, allow them to callous for a day or two, then pot each in fresh succulent mix.

Q: Can this plant survive outdoors?
A: Star Window Plant grows outdoors in USDA zones 911 across much of the Sun Belt. Move it to a sheltered location, shield it from rain, and protect it from harsh afternoon sun.
