Haworthiopsis attenuata, formerly Haworthia attenuata, commonly known as zebra haworthia, is a small species of succulent plant from the Eastern Cape Province, South Africa. As an ornamental, it is one of the most commonly cultivated of the Haworthiopsis species.

Description

It is an evergreen succulent plant with short leaves arranged in rosettes 6–12 cm in diameter. The succulent leaves are tapered ("attenuata" means "tapering") and have bands of white tubercles on them. The species subdivides and offsets readily; in the wild it forms large clumps. Their flowers appear in spring (November and December in the southern hemisphere). It is popular as a house plant, due to its resistance to drought and general hardiness.

It is frequently confused with the rarer Haworthiopsis fasciata , to which it looks very similar. However, Haworthiopsis attenuata can easily be distinguished by its white tubercles, which occur on both upper and lower sides of its leaves (H. fasciata has tubercles only on the underside, with a smooth upper surface of its leaves). A fundamental distinction is that the leaves of H. attenuata are not fibrous. In addition, the leaves of H. attenuata are often (though not always) longer, thinner, and more splayed out. [2] [3]

Varieties

It is a variable species. As of September 2024, Plants of the World Online accepted three varieties: [4]

A common variety is Haworthiopsis attenuata var. radula – hankey dwarf aloe (previously considered a separate species), which has longer, more elongated, scabrid leaves than the type H. attenuata var. attenuata, with smaller, more numerous tubercles. This variation grows up to 6 inches (15 cm) in diameter and up to 6 inches (15 cm) tall.[ citation needed ]H. attenuata var. glabrata has been considered to be the separate species Haworthia glabrata when Haworthiopsis was not distinguished from Haworthia. [5]

Cultivation

Like most succulents, Haworthiopsis attenuata plants prefer soil with adequate drainage, such as cactus mix or fast-draining potting soil mixed with sand. They like bright light, but too much direct sunlight can cause leaves to turn white or yellow. The plants should be watered evenly and generously during the summer, allowing the soil to dry out between watering. In the winter, they can be watered as infrequently as once every two weeks.

<i>Agave attenuata</i> Species of flowering plant

Agave attenuata, commonly called the foxtail or lion's tailagave or the swan's neck agave, is a species of flowering plant in the family Asparagaceae. Sometimes called the soft-leaf or soft-leaved agave, the aforementioned animal-related names are a nod to the appearance of the plant's inflorescence, which—after years, generally—rises slightly before gravity brings it back down, giving the bloom a curved, "swan"-like or "foxtail" look. The species' specific manner of flowering is unique in the genus Agave as most other species produce a towering, vertical display, reminiscent of a miniature tree.

<span class="mw-page-title-main">Aloeae</span> Tribe of succulent plants

Aloeae is a tribe of succulent plants in the subfamily Asphodeloideae of the family Asphodelaceae, consisting of the aloes and their close relatives. The taxon may also be treated as the subfamily Alooideae by those botanists who retain the narrower circumscription of Asphodelaceae adopted prior to the APG III system. Typically, plants have rosettes of more or less succulent leaves, with or without a distinct stem. Their flowers are arranged in racemes and tend to be either small and pale, pollinated by insects, or larger and more brightly coloured, pollinated by birds. As of 2017, 11 genera are recognized, most created since 2010 by splitting off another five genera from Aloe and another two from Haworthia. Only two genera, Aloe and Aloidendron, are native outside southern Africa, extending northwards to the Arabian Peninsula. Seven genera are restricted to South Africa, some with small ranges. Members of the Aloeae are cultivated by succulent plant enthusiasts; Aloe species especially are used in temperate climates as ornamental garden plants. Some species are used in traditional medicine. Aloe vera and Aloe ferox are cultivated for their extracts, whose uses include moisturizers and emollients in cosmetics.

<i>Haworthiopsis</i> Genus of succulent plants

Haworthiopsis is a genus of succulent plants in the subfamily Asphodeloideae. The genus was previously included in Haworthia. Species in the genus are typically short perennial plants, with leaves often arranged in a rosette and frequently having raised white markings. The two-lipped flowers are borne on a tall stalk and are small – less than 17 mm (0.7 in) long – and pale in colour. Many species are cultivated as house plants or by succulent enthusiasts.

<i>Haworthia reticulata</i> Species of plant

Haworthia reticulata is a species of succulent plant native to the southwestern Cape Provinces of South Africa. The species has several varieties, including var. hurlingii which is the smallest at up to 1 inch (2.5 cm) wide.
