Scientific Name

Haworthia mutica Haw.


Haworthia mutica var. mutica, Haworthia groenewaldii, Aloe mutica, Haworthia otzenii, Haworthia retusa var. mutica

Scientific Classification

Family: Asphodelaceae
Subfamily: Asphodeloideae
Tribe: Aloeae
Genus: Haworthia


Haworthia mutica is a succulent plant with compact, flattened rosettes, up to 3.2 inches (8 cm) in diameter, of prominently windowed leaves. It is a variable species, sometimes difficult to distinguish from Haworthia retusa and Haworthia pygmaea. The leaves are thick, truncated and triangular at apex, glaucous grey-green or glossy dark green with a characteristic bluish-brown coloration, often developing purplish cloudiness and striped in subtle shades of green. The tips are transparent and act like windows, allowing sun to enter inside of the leaf for chlorophyll processing. The flowers are small, two-lipped, greenish-white with pale purplish veins and appear mainly in summer.


USDA hardiness zones 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 decorative, little plants can be grown in interesting containers such as tea cups and even miniature baby shoes. If you're given a Haworthia in such a container, make sure the container had adequate drainage.

Haworthias are small, usually remaining between 3 and 5 inches (7.5 cm and 12.5 cm) in height, and relatively slow-growing. They are often grown in small clusters in wide, shallow dishes. Over time, clusters will naturally enlarge as the mother plant sends off small plantlets. When the cluster has outgrown its dish, repot in the spring or early summer into a new wide and shallow dish with fresh potting soil. This is also the time to take offsets for propagation.

Haworthia mutica is native to South Africa (Western Cape).

Product Details


Haworthia mutica (Haworth): Striped, chunky green leaves form a loose rosette. Each leaf has a flat top with a translucent "leaf window" that lets sunlight into the leaf interior. With brighter light it can take on a copper or purple coloration.

Haworthia are able to tolerate low, indoor light, making them excellent houseplants, even for beginners. They are particularly easy to grow and rarely affected by common succulent pests and diseases. Strong, drought-tolerant roots will grow if they have great drainage and infrequent water. Pick deep containers with drainage holes and a gritty, well-draining soil that is 50% to 70% mineral grit (coarse sand, pumice, or perlite). Water deeply enough for water to run out the drainage hole and allow the soil to completely dry before watering again.

This genus tolerates high heat by slowing down and eventually going dormant in the peak of summer. This means that, unlike other succulents, it is important not to over-water or fertilize during summer dormancy and water a bit more frequently in the winter growing season. Haworthia are slow growers and tend to stay small in pots, but they will produce new offsets in clumps around their bases. These offsets can be left to develop into a dense clump or pulled off and transplanted.

Haworthia mutica - garden

Origin and Habitat: South Africa (Western Cape: Overberg)
Habitat: Haworthia mutica grows almost buried in the ground on rocky shale ridges often in crevices. It shares its distribution area with Haworthia maraisii, Haworthia russouwii, Haworthia modesta, Haworthia heidelbergensis var. minor and Gasteria carinata. In many other embedded plant forms, including Bulbine mesembryanthemoides and many species of Opthalmophyllum and Lithops, light reaches internal chloroplasts in the buried leaf through windows of unpigmented cells on the exposed leaf tips. Small succulents resemble the soil, stones or dung of their habitats, or the shadows and woody stems of the shrubs that shelter them. Individuals that escape predation may be remarkably long-lived, up to 95 years in the case of Lithops plants.

Description: Haworthia mutica is one of the retuse-leaved haworthias, with compact flattened rosettes of prominently windowed leaves. It is mainly a non-proliferous species that do not offsets or offsets slowly, but most of the plants in cultivation derives from very prolific clones and form soon dense clumps. It is a variable species sometimes difficult to distinguish from to Haworthia retusa and Haworthia pygmaea.
Leaves: Thick geometric, truncated and triangular at apex, glaucous grey-green or glossy dark green with a characteristic bluish-brown colouration, often developing purplish cloudiness and striped in subtle shades of green. The tips are transparent and act like windows, allowing sun to enter inside of the leaf for chlorophyll processing.
Flowers: Small, two-lipped, greenish-white with pale purplish veins.
Blooming season: Mainly in Summer but it may flowers in any favourable season.

Cultivation and Propagation: Haworthia mutica grows best in bright but indirect, or moderate light or redden nicely in full sun. It grows without any major problems in cultivation and is an ideal small indoor plant. Outdoors it suit in rockeries, but avoid frost.
Soil: They are slow growing and prefer a porous, well-draining soil.
Moisture: They need regular water, but don't let the soil be constantly moist or soggy and while not wanting to be excessively wet, they will be equally unhappy if the soil is kept dry for long periods.
Hardiness: They do best in warm dry climates. Frost Tolerance: -1.C° (or less for short periods).
Propagation: They should be propagated by seeds or vegetatively by leave cuttings or division of larger clumps.
