Origin
Haworthiopsis nigra var. diversifolia is native to South Africa. It grows under the bushes or amongst stones from Leeu Gamka to Beaufort West in the Western Cape province.
Description
Haworthiopsis nigra var. diversifolia, formerly known as Haworthia nigra var. diversifolia, is a small succulent with dark grayish-green, leathery leaves tightly arranged on the stem. It slowly grows, solitary or in small clumps, and can reach up to 2 inches (5 cm) in height. In this variety, the tubercles are flattened, often confluent in transverse bands, and tend to be greyish, while the leaves are shorter and more closely adherent. Because the leaves are short and only slightly recurved at the tips, their arrangement in three vertical tiers is very obvious.
In late spring or summer, mature rosettes produce simple, lax stalks with small white flowers.
Hardiness
USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
These succulents are not considered difficult houseplants to grow. If you can keep a pot of Aloe alive on a windowsill, chances are you can do the same with a dish of Haworthia. As with all succulents, the most dangerous situation is too much water. They should never be allowed to sit in water under any circumstances. At the same time, these little decorative plants can be grown in interesting containers such as teacups and even miniature baby shoes. If you're given a Haworthia in such a container, ensure the container has adequate drainage.
Haworthias are small, usually between 3 and 5 inches (7.5 cm and 12.5 cm) in height, and relatively slow-growing. Therefore, they are often grown in small clusters in wide, shallow containers. Over time, clusters will naturally enlarge as the mother plant sends off small plantlets. When the cluster has outgrown its container, repot into a new wide and shallow dish with fresh potting soil in the spring or early summer. This is also the time to take offsets for propagation.
