Haworthia Cooperi Succulent

It forms tight, upright rosettes of plump forest green leaves tipped with soft bristles. The leaves have translucent tips called “windows” that catch light, giving each rosette a jewel-like appearance. Haworthia Cooperi stays compact and sculptural, reaching only 24 inches tall, and fits perfectly in terrariums, small pots, or shelf displays without crowding its neighbors.

In spring or summer, it produces slender flower spikes with small tubular white blooms, often triggered by a slight drop in nighttime temperatures. The flowers are modest rather than showy, but they confirm the plant is growing well. Between bloom cycles, the translucent foliage is the main feature.

Move it outside in summer to a bright, sheltered spot with indirect light, keeping it covered from rain and bringing it indoors before frost arrives. It is pet-friendly and safe for homes with cats and dogs. The plant handles dry heated indoor air well. You can leave it up to ten days without water.

Water it every 23 weeks during the growing season, letting the soil dry completely between waterings; reduce to once a month in winter.

Haworthia Cooperi does best in a fast-draining cactus and succulent mix combined with extra perlite for improved drainage.

It prefers temperatures between 6580F and should be protected from frost below 30F.

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

It is hardy in USDA zones 911, tolerating brief dips to around 30F but suffering damage with prolonged frost. It grows outdoors year-round in California, Arizona, Texas, Florida, Hawaii, Louisiana, Georgia, South Carolina, Alabama, Mississippi, and Nevada. Parts of Oregon, New Mexico, and coastal areas of North Carolina also fall within these zones.

Q: How often should I water Haworthia Cooperi Succulent?
