Haworthiopsis attenuata · also called Zebra plant, Zebra cactus, Haworthia attenuata, Star window plant
🐾 Pet-safe
Generally non-toxic to cats and dogs.
A small, slow-growing rosette of stiff, dark-green leaves banded with raised white 'zebra' stripes, Haworthiopsis attenuata is a pet-safe, low-light-tolerant succulent ideal for desks and windowsills. It stays compact and rarely outgrows its pot.

Light
Unlike most succulents, zebra haworthia tolerates and even prefers bright indirect light rather than scorching full sun, which can bleach or redden its leaves. An east-facing window or a bright spot out of harsh midday rays is ideal, and it copes with lower light better than echeveria or aloe. Leaves that turn red or yellow usually signal too much direct sun.
Water
Water thoroughly, then let the soil dry out completely before watering again; like all succulents it rots if kept wet. Because it is small and slow, it needs less water than larger succulents — err on the side of underwatering, especially in winter when growth nearly stops. Avoid letting water sit in the tight rosette.
Soil & potting
Grow in a gritty, very free-draining succulent or cactus mix with extra perlite or pumice, in a small pot with a drainage hole. Its root system is modest, so it does well in a snug container and resents being overpotted in a large volume of slow-drying soil. Repot only every few years.
Environment — humidity, temperature, placement
Haworthia likes warm, dry, ordinary indoor air and does not need or want humidity. It is frost-tender; keep it above roughly 50F (10C) and away from cold drafts. Good airflow and a dry rosette help prevent rot — a tidy, undemanding plant for typical home conditions.
Propagation
It propagates most easily from offsets: mature plants cluster small pups around the base, which can be separated with a few roots and potted individually. Leaf propagation is far less reliable than with echeveria — the stiff leaves often fail to root — so offsets are the practical route. Let any separated pup's cut surface dry briefly before potting and watering lightly.
Toxicity detail
Safe (non-toxic) to cats and dogs. Haworthia is not listed among the ASPCA's toxic plants and is widely regarded as non-toxic to pets, making the zebra haworthia a good choice for cat and dog households. It contains no known toxic compounds, though eating a large amount of any plant material can cause mild, temporary digestive upset.

Origin & history
Native to South Africa's Eastern Cape, this species was long known as Haworthia attenuata and was reclassified into the genus Haworthiopsis as botanists refined the group; both names remain in common use. The genus honors the British botanist Adrian Hardy Haworth, an early authority on succulents. Its small size, tolerance of indoor light, and pet-safety have made the 'zebra plant' one of the most popular beginner succulents worldwide.
Growth stages
How this plant changes through its life — each stage often has its own care, diet and space needs.

Seed
Most plants begin as a seed (or spore in ferns) — a dormant package holding the embryo and a food reserve within a protective coat. Given moisture, warmth, and sometimes light, the seed breaks dormancy and germinates.
Photo coming soon
Seedling
The seedling emerges with a root and its first leaves (cotyledons), then true leaves. It is tender and shallow-rooted, dependent on steady moisture and light as it establishes the beginnings of stem and root systems.

Vegetative growth
In the vegetative phase the plant focuses on growing roots, stems, and foliage, building the size and structure it needs before flowering. This is the main period of leafing out and, for many houseplants, the stage at which they are grown and propagated.
Mature / Flowering
A mature plant reaches its full habit and, when conditions and age allow, flowers and sets seed (or, for foliage plants, simply attains its full adult size and form). This is the stage shown in most reference photos.
Problems & solutions
Each problem lists a proven fix (horticulture / extension-backed) and, where useful, an anecdotal remedy from the grower community — clearly labeled so you can judge for yourself.
Leaves turn red, brown, or bleached (too much sun)
mild
Symptoms:The normally dark-green leaves flush red, purple, brown, or pale and washed-out.
Likely cause:Excessive direct sunlight. Zebra haworthia prefers bright indirect light, and intense sun stresses or scorches the foliage.
✓ Proven fix
Move the plant out of harsh direct sun into bright indirect light. Mild discoloration usually fades as the plant recovers; badly scorched tissue will not green up again and can be trimmed for appearance.
◇ Anecdotal remedy — grower lore, unverified
Some growers accept a slight reddish blush as a harmless 'tan' and simply pull the plant a foot back from a hot window rather than into deep shade.
Soft, translucent, rotting leaves
severe
Symptoms:Lower or inner leaves become mushy, yellow-brown, and translucent, and the rosette loosens or topples.
Likely cause:Overwatering, an overly large pot of slow-drying soil, or water sitting in the rosette — all keeping the small root system too wet.
✓ Proven fix
Let the mix dry fully between waterings, use a small pot with gritty fast-draining soil, and water at the soil line. Remove rotted leaves; if the base is affected, separate and re-root healthy offsets to preserve the plant.
◇ Anecdotal remedy — grower lore, unverified
Because the plant is so slow, many keepers water it noticeably less than their other succulents and report that 'almost forgetting it' keeps it healthiest.
Shriveled, curling leaves
mild
Symptoms:Leaves thin out, wrinkle, or curl inward and the rosette looks deflated.
Likely cause:Underwatering or a completely dried-out rootball over a long period, drawing down the leaves' water stores. Dead roots from earlier overwatering can also prevent uptake.
✓ Proven fix
Water thoroughly and the leaves should plump back up within days if roots are healthy. If they stay shriveled, check the roots for rot and re-root a healthy offset or rosette if necessary.
◇ Anecdotal remedy — grower lore, unverified
Growers note that haworthia bounces back from neglect so readily that a slightly shriveled plant is nothing to worry about — a soak usually restores it overnight.
Anecdotes & grower lore
Community experience and cultural notes — not horticultural guarantees. Conditions vary by home; treat these as colour, not prescriptions.
Haworthia is the succulent people reach for when their window 'isn't sunny enough for the others' — growers pass it along as the plant that survives a north-facing office desk where echeverias sulk. Its raised white stripes lead newcomers to mistake it for a tiny aloe or a cactus, and collectors of the see-through 'window-leaved' haworthias speak almost reverently of the translucent panels that let light into the buried leaves of desert relatives.
