Haworthia cooperi is a low growing densely clustered succulent which rosettes are usually withdrawn in the soil. Its short stem is located several centimetres underground, and produces many cylindrical leaves that are just long enough to reach the soil surface, the transparent tips allowing light into the factory below. In transverse section the leaf is so transparent you can read through it. It is excellent for transmitting light to parts of the leaf that are underground. It was introduced into cultivation by Cooper in 1860.

Variegated form(s): The pale foliage is distinctively patterned with a consistent, whitish-grey, variegation. It slowly forms offsets, becoming an attractive clump in time. Individual plants can vary a lot depending on the care they've received, especially the amount of light.

Growing Conditions

Light: Bright light, but not direct sunlight. These grow in similar conditions to other succulents. White or yellow leaves usually signify too much sun.
Water: Water evenly and generously in the summer, letting the soil media dry out between watering. In the winter, reduce watering to every other month. Never allow water to collect in the rosette.
Temperature: Warmer summers but cool in the winter (down to 50˚F/10˚C).
Soil: Use a cactus mix or very fast-draining potting soil mixed with sand.
Fertilizer: Fertilize during the summer growing season with a cactus fertilizer. Don’t feed during the winter.

Propagation

Haworthia can be propagated at repotting time using offsets from the mother plant. When taking offsets, use a sharp knife or snippers and cut as close to the mother stem as possible to including as many roots as possible, then allow the offset to dry briefly before repotting it (similar to cuttings from other succulents).

Pot the offsets in a small pot, using the same soil as the mother plant, put it a warm, bright spot, and make sure to adequately water.
