Haworthiopsis glauca var. herrei, formerly known as Haworthia glauca var. herrei, is a small succulent, up to 6 inches (15 cm) tall and branching at the base to form clumps of rosettes on elongated stems. Leaves are erect, dark green to grey-green, with pointed tips and ridges on outside. Inflorescence stands up to 16 inches (40 cm) tall. Its single raceme is up to 5.2 inches (13 cm) long and bears from 13 to 20 white, spirally arranged flowers.
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Haworthiopsis are best suited to container gardening. In frost-free areas with a lower rainfall, some of them can be grown successfully in rockeries when planted in sheltered areas amongst rocks, where they will form clumps or clusters over time.
Even though most species are hardy and can tolerate full sun, they flourish in semi-shaded positions, but brighter light conditions are needed to bring out the leaf coloration. Any window in your house or office is likely to be an appropriate setting for Haworthiopsis.
These succulents can be planted in terracotta pots using a well-drained potting soil.
As with all succulents, the most dangerous situation is too much water. The best way to water these succulents is to use "soak and dry" method. Get the soil completely wet and then wait until the soil is dry before watering again. In the winter, reduce watering to once per month. Never allow water to collect in the rosette.
