Haworthia cooperi var. truncata 'Alien Eggs' is a rare succulent from the Eastern Cape of South Africa, where it grows nestled into rocky, shaded soil. It is sought after by collectors worldwide for its distinctive appearance and compact form.
The leaves are compact and nearly flat-topped, with glassy green window tips that glow when backlit. Each rosette clusters tightly with offsets over time, building into a cushion of dome-shaped leaves that resemble alien eggs. The translucent windows allow light to filter into the leaf tissue, a natural adaptation that reduces water loss in its native rocky habitat.
A slight drop in nighttime temperature encourages blooming, typically producing slender white flowers on tall stalks in spring or summer. It is non-toxic and pet-safe for cats and dogs.
You can leave it up to ten days without water. Haworthia Cooperi Truncata adapts well to office LEDs or a kitchen windowsill where gentle ambient moisture helps it grow well. Move it outside in summer in warm climates as long as it stays covered from rain. It stays small, typically reaching 2 to 3 inches tall per rosette. It works well in terrariums, shallow dish gardens, or as a windowsill specimen.

Haworthia cooperi var. truncata 'Alien Eggs' grows in low, medium, or bright indirect light, avoiding direct sun that scorches the translucent leaf tips.
Water it every 2 to 3 weeks in summer and once a month or less in winter, allowing soil to dry fully between waterings.
Haworthia Cooperi Truncata does best in a fast-draining mix of cactus soil blended with perlite or coarse grit at roughly 50/50 ratio.
It prefers temperatures between 65 to 85°F and should be kept above 40°F, as it is frost tender.
