Accepted Scientific Name

Catevala greenii, Haworthia coarctata var. greenii, Haworthia coarctata f. greenii, Haworthia greenii, Haworthia reinwardtii var. greenii
Haworthiopsis coarctata f. greenii, formerly known as Haworthia coarctata f. greenii, is a small succulent that forms dense clumps of elongated rosettes of fleshy, usually dark green leaves without or with very few white tubercles. The rosettes can grow up to 8 inches (20 cm) tall, offsetting at the base. When exposed to full sun, the leaves take on a reddish-brown hue.
The plant blooms from late spring to fall. The mature rosettes produce whiplike flower stalks reaching 12 inches (30 cm) long and bearing tiny greenish-white, tubular flowers.
Haworthiopsis coarctata f. greenii is a form of Haworthiopsis coarctata var. coarctata with smooth leaves with tubercles mostly absent. Its distribution is limited to a small area west of Makhanda, commonly known as Grahamstown, in the Eastern Cape province of South Africa.
USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °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 container with fresh potting soil in the spring or early summer. This is also the time to take offsets for propagation.
