Haworthiopsis limifolia

Where it grows in the wild

Haworthiopsis limifolia occurs in southern Mozambique, Eswatini and northeastern South Africa. It inhabits elevated grassland on hilltops and ridges, usually sheltered among stones and grasses at about 300 to 800 m. Populations vary across this range, and several varieties and other forms below species level have been named.

Older references use the name Haworthia limifolia. The move to Haworthiopsis reflects the modern separation of this group from the broader traditional genus Haworthia. In South Africa the species is assessed as Vulnerable, with a decline of more than 30% estimated over 60 years. Harvesting for traditional medicine is a major pressure, joined by collection for cultivation, habitat destruction, overgrazing and invasive plants.

Care for water-storing roots and leaves

Watering and root care: The thick storage roots of Haworthiopsis limifolia need air as well as water. Soak them while the rosette is growing, then let the mix approach dryness before watering again. When cool winter conditions slow the plant, give only occasional moisture to prevent severe shrivelling because persistent wetness can suffocate the resting roots.

Root care, watering and repotting: Use a highly porous peat-free cactus mix with a substantial mineral component and complete drainage. Repot gently in spring only when the roots or offsets need more room, removing nothing except clearly dead or hollow roots. A deep oversized pot stays wet too long, and the lowest leaves should remain above the potting mix.

Feeding and propagation: Feed lightly during spring and summer growth, then omit fertiliser in winter. Rooted offsets can be separated. Seed-grown plants naturally vary, so seedlings may not match the parent plant.

Light: A bright, filtered position or gradually introduced gentle sun keeps the ridged leaves compact.

Finding the cause of plant problems

A wrinkled Haworthiopsis limifolia that does not plump after watering may have lost its storage roots. Repeated watering can then worsen the problem. Inspect for firm viable roots, remove only dead hollow tissue and restart the plant in a highly open dry mix before watering cautiously. Rapidly spreading translucence at the base is rot, whereas slow dryness on the oldest outer leaves can be normal ageing. Keep the lower rosette above the mix and prevent water from remaining around the crown.

A stretched, flattened rosette points to insufficient light. Papery bleached areas appearing after a sudden move indicate scorch. Increase exposure in stages and judge recovery from compact new leaves, since existing scars will not turn green again.

White waxy material on the roots may be root mealybugs and requires quarantine plus treatment below the soil line. The transverse ridges belong to healthy leaves and should not be mistaken for pest scarring. A long flower stalk is normal reproductive growth, not stretching of the rosette itself.

Haworthiopsis limifolia has sharp parts

• This plant is non-toxic to cats and dogs. Its effects on people are unclear.
• Rigid leaf tips and toothed margins can scratch or puncture the mouth, eyes, skin or paws.
• Handle it carefully. Contact a veterinarian or medical professional after a serious injury, especially to the eye.

Who first published Haworthiopsis limifolia, and what does the name mean?

Haworthiopsis combines Haworthia with the Greek suffix -opsis, meaning appearance or resemblance. Limifolia combines Latin lima, meaning file, with folium, meaning leaf.

Gordon Douglas Rowley established the genus Haworthiopsis in 2013 in Alsterworthia Int, Special Issue 10, page 4.

Hermann Wilhelm Rudolf Marloth first described it as Haworthia limifolia in 1910 in Transactions of the Royal Society of South Africa, volume 1, page 409. Gordon Douglas Rowley later placed it in Haworthiopsis as Haworthiopsis limifolia in 2013 in Alsterworthia Int, Special Issue 10, page 4.
