Haworthia venosa subsp. tessellata is one of the most widespread and also it is a very variable succulent plant. It is a slow-growing, stemless evergreen up to 6 inches (15 cm) tall and up to 4 inches (10 cm) in diameter with about 7-15 leaves arranged in spirals. The leaves are sessile, up to 2 inches (5 cm) long, up to 1.2 inches (3 cm) wide at the base, fleshy, firm in texture, broadly triangular, strongly recurved, brownish to green, cuspidate at the apex. The upper surface is marked with 6 pale green, anastomosing, vertical lines, forming a square patterned design and windowed. The lower surface is usually rounded slightly scabrid with raised coriaceous tubercles, especially in the upper part where they are arranged in transverse rows, margins with recurved white teeth. The leaves are greenish, form a rosette and turn to reddish in full sun. Small, tubular, white flowers with green bibs appear in summer, on a few flowered simple raceme up to 20 inches (50 cm) tall.

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.
