Haworthiopsis tessellata is a hardy, mat-forming succulent from southern Africa, easily recognised by the net-like pattern of translucent veins etched across the upper surface of its leaves. The stiff, recurved leaves and this tessellated "windowed" marking give the species its name and make it one of the more distinctive small succulents in the Haworthiopsis genus.
Description
Haworthiopsis tessellata forms low rosettes of firm, triangular leaves that typically curve backward (recurve) toward the soil, giving the plant a flattened, spreading profile. The leaves are usually dark green to brownish, often taking on reddish or purplish tones in strong light, and their margins may carry small teeth.
The defining feature is the leaf surface: the upper face is marked with a distinctive network of pale, translucent lines — the tessellation — that resembles the mesh of a net or the panes of a stained-glass window. These translucent "windows" are thought to help channel light into the leaf. Over time the plant offsets freely from the base, spreading into a dense clump or mat rather than remaining a single rosette.
Distribution and habitat
The species is native to the arid interior of southern Africa, occurring across parts of South Africa and into Namibia. It grows in dry, rocky terrain, often nestled among stones or beneath the light shade of nurse shrubs where it is partly protected from the fiercest sun. In habitat the plants frequently sit low against the ground, with the flat, veined leaf tops exposed while the rest of the rosette hunkers into gritty soil and rock crevices.
This wide, rugged range is part of why the species has a reputation for toughness among growers.
Cultivation
Haworthiopsis tessellata is one of the more forgiving members of its genus and a good choice for beginners. Grow it in a gritty, free-draining mix and water thoroughly only once the soil has dried out completely, easing off almost entirely through the cool winter months. Overwatering — especially in a heavy, slow-draining mix — is the main cause of loss, so err on the dry side.
Unlike the softer, more shade-loving haworthias, this species tolerates and even appreciates brighter conditions; good light keeps the rosettes compact and brings out reddish leaf tones and crisper vein patterning. A little protection from the most intense afternoon sun helps prevent scorching. See Watering and Repotting for general technique, and note that clumps are easily divided when they outgrow their pot.
Propagation
The easiest method is by offsets: mature clumps produce pups readily around the base, which can be separated with a few roots and potted individually. Allow any cut or torn surfaces to callous briefly before potting into a dry, gritty mix, then water sparingly until established.
The species can also be raised from seed, though this is slower and less common in general cultivation. See Propagation — seed for the seed-sowing method.
Common problems
- Rot — usually from overwatering or a slow-draining mix; the rosette softens and browns, often from the base. Keep the plant dry in winter.
- Shrivelled, faded leaves — a sign of underwatering or too much heat; the leaves lose plumpness and the vein pattern dulls.
- Pests — mealybugs (white fluff between the leaves and at the roots) and the occasional fungus gnat in overly damp soil are the usual offenders. See Pests and diseases.
