Summary
Cooper's Haworthia is a slow-growing succulent native to the Eastern Cape of South Africa, forming compact rosettes of fleshy leaves with translucent tips that resemble glass windows and producing small white to pinkish-white flowers on stalks.
It prefers bright, indirect light with well-draining soil and terracotta pots for drainage; water thoroughly only after the substrate dries completely, and reduce watering in winter; repot every 2–3 years and propagate easily from offsets or leaf cuttings; commonly used in indoor pots and terrariums, and it is non-toxic.
