Haworthia cooperi originates from coastal South African habitats featuring sandy soils and volcanic rocks. It exhibits a clumping, polycarpic growth habit with translucent leaves that enhance photosynthesis under diffused light, a unique trait within its genus. Leaves cylindrical, fleshy, 2-3 cm long, arranged in a dense rosette; translucent tips with faintly serrated margins; light green color turning duller under direct sunlight.
Needs filtered light, avoiding more than 4 hours of direct sun; watering restricted to active growth in spring-summer; substrate with minimum 70% mineral content ensuring drainage; minimum temperature 5°C; root rot risk from waterlogging.
