Overview
Haworthia is a small rosette succulent from the dry corners of southern Africa, and it may just be the most forgiving houseplant you ever bring home. Its fleshy leaves gather into snug little stars, and many of them carry translucent leaf windows at the tips that seem to glow when the light hits them. Best of all, it stays small and tidy for years, reaching only about 3 to 6 inches (8 to 15 cm) across, so there is very little that can go wrong.
What makes it such a comforting plant to start with is how kindly it takes to shade. In the wild it grows sheltered among rocks and grasses in part shade, which means it copes with the softer light of an everyday room far better than a sun-loving echeveria ever could. If a dim windowsill has claimed plants for you before, this is a gentle place to rebuild your confidence.
The one thing it truly minds is a wet pot, and once you know that, you already have the hardest part figured out. Haworthia is made to wait out dry spells and tucks water away in its leaves, so it would always rather be a bit dry than damp. Get the watering right and everything else falls into place, with unhurried growth and a friendly cluster of offset pups that quietly turn your one plant into several.
Care
The short version: give it bright indirect light, a gritty fast-draining mix, and one good soak only after the soil has dried right through. Go easy in winter, feed lightly through the growing season, and never leave it sitting in water and you will do just fine.
Light
Set it in bright indirect light by a window that misses the harsh midday sun and it will be content. It hangs on in medium or even low light better than almost any other succulent, so do not stress about the perfect spot, though too much direct sun can turn the leaves red or brown.
Water
Let the soil dry out completely before you water, then soak it well until it runs from the bottom. In the growing season that usually lands around every 14 to 21 days, and much less in winter. Since this plant is highly prone to root rot, when you are unsure it is always safe to simply wait.
Soil
Pot it up in a gritty cactus or succulent mix that drains fast and never turns soggy. Any pH from 6.0 to 7.5 will keep it happy, and honestly a pot with drainage holes matters far more than fussing over the exact recipe.
Temperature
Ordinary room warmth is perfect, somewhere between 59°F and 81°F (15°C to 27°C), so wherever you are comfortable it will be too. Just keep it clear of cold drafts and frost, since it cannot handle freezing.
Humidity
Plain low household humidity is exactly what it likes, which means no trays or misting to keep up with. Dry air suits it beautifully, and as a bonus it helps hold rot at bay.
Feeding
Feed it gently through spring and summer while it is growing, using a balanced liquid fertilizer at half strength. One light feeding now and then across the season is plenty for such a slow grower, and it needs nothing at all in winter, so there is no pressure here.
Pruning
There is next to nothing to do on this front. Simply pull away the dead, dried, or damaged outer leaves and trim off spent flower stalks once they finish, and the plant looks after the rest.
Repotting
Move it up every 2 to 3 years, or a touch sooner once offsets start to crowd and lift out of the pot. Roots peeking through the drainage holes or soil that dries out unusually fast are your other friendly hints that it is ready for a fresh home.
Size & spacing
This is a small, easygoing plant, topping out at just 3 to 6 inches (8 to 15 cm) tall and about as wide. A cozy pot suits it well, and a little group can happily share one shallow dish with just a bit of breathing room between the rosettes.
Troubleshooting
Almost every haworthia hiccup comes down to water or light, and the good news is the plant lets you know early and forgives you quickly. Look closely at the leaves and the rosette, find the matching signs below, and you will have it sorted before anything serious sets in.
Soft, dark leaf bases with the center caving in
Take heart, because this looks scary but you caught it, and that matters. What you are seeing is root and crown rot, which sets in when the roots stay stuck in wet, slow soil. Gently lift the plant, trim off every soft brown root with a clean blade, let those cuts dry over, and settle it back into dry gritty mix.
Fix:
- Stop watering immediately
- Unpot and cut away all soft, rotted roots and tissue with a clean blade
- Allow cuts to callus, then repot into fresh dry gritty mix
- Resume watering only sparingly once established
Wrinkling leaves that have gone soft and thin
Do not worry, this one is an easy fix and the plant recovers beautifully. Your thirsty haworthia is simply drawing on the water stored in its own leaves. Feel the soil to be sure it is bone dry the whole way down, give it a slow thorough drink until water runs out the bottom, and watch the leaves fill back out over the next few days.
Fix:
- Water thoroughly until it drains from the bottom
- Allow excess to drain fully
- Return to a regular dry-then-water cycle
A warm red, orange, or brown flush on the leaves
This is nothing to panic over, and it will not spread the way a disease might. Your plant is catching a little too much direct sun, which shows up first on the leaves nearest the glass as sun stress. Slide it back into gentle bright indirect light, and while those marked leaves stay as they are, the new growth comes in fresh and green.
Fix:
- Move the plant to bright indirect light
- Shade from intense midday sun
- Damaged leaves will not recover but new growth returns to normal color
A pale, stretched rosette with the leaves spreading apart
This just means your plant is quietly asking for more light, and it is easy to give. Reaching for a brighter spot causes the stretching known as etiolation, so the rosette fades, tips toward the window, and its snug leaves loosen and gap. Move it somewhere with strong indirect light and give the pot a quarter turn every so often, and it will settle back into shape as it grows.
Fix:
- Move to a brighter spot with bright indirect light
- Rotate the pot regularly for even growth
Toxicity
Here is a lovely bit of reassurance for a houseplant: haworthia is non-toxic and pet-safe. It does not appear on the ASPCA's toxic list, and there is nothing in the leaves to hurt a cat, a dog, or a curious little one. At most a stray nibble might bring a brief stomach ache from the fibrous tissue, and nothing more.
Safe for
People · Cats · Dogs · Horses · Rabbits · Livestock · Birds
Cats None
You can relax with a cat in the house. If yours steals a curious nibble, the most it might get is a little passing tummy upset, with nothing poisonous involved.
Dogs None
Your dog is in no danger from this one. A stubborn chewer might feel a touch queasy from the fibrous leaves, and that really is as far as it goes.
Horses None
Nothing here will harm a horse, though such a tiny plant is far too small for one to take any interest in.
Rabbits None
No need to fret if a rabbit sneaks a bite. Those thick succulent leaves carry no toxins at all.
Livestock None
There is no risk to grazing animals, and kept as an indoor pot plant it almost never ends up within their reach.
Birds None
Your pet birds are perfectly safe beside it. The leaves hold no toxic compounds to give you any concern.
People None
It poses no poisoning risk to people, little ones included. Nobody grows it to eat, so there is no reason to taste it, but an accidental nibble will do no harm.
Varieties
The genus holds dozens of species, but only a handful keep turning up on windowsills. These are the friendly few worth learning by name as you get started.
Haworthia cooperi
You will love how its plump, rounded leaves end in see-through windows that light up when the sun reaches them from behind.
Haworthia cymbiformis
Its boat-shaped leaves nestle into a tidy rosette, and each one shows soft window markings toward the tip.
Haworthia retusa
This one greets you as a star-shaped rosette of triangular leaves, their flat upper faces staying clear and translucent.
Haworthia truncata
Its leaves seem cut off flat across windowed tops, sitting side by side much like a row of a horse's teeth.
How to propagate
Haworthia makes more of itself with barely any help from you, and once you have one settled in, you may never need to buy another. It is honestly one of the most rewarding first plants to multiply.
Offsets & pupsEasy
Spring to summer during active growth · 4 to 8 weeks to root
The kindest place to start is with the offsets, those little pups clustering at the base, gathered in spring or summer while the plant is growing. Ease them away from the parent, let the cut ends dry over for a day or two, and tuck each into dry gritty mix. Give them time and they root in around 4 to 8 weeks, so you really cannot go wrong.
DivisionEasy
Spring, often at repotting · 4 to 8 weeks
Once a clump has filled out into several crowded rosettes, you can split it in spring while you have it out for repotting anyway. Work the roots gently apart so each rosette keeps a share of its own, then pot them up on their own. They usually settle in comfortably over about 4 to 8 weeks.
Leaf cuttingsModerate
Spring to summer · Several weeks to a few months
If you feel like experimenting, you can raise a whole new plant from one leaf in spring or summer. Pull a healthy leaf away in full, let it callus, and rest it on dry mix. It is slower and less sure than the pups, and it may take several weeks to a few months to show roots, so treat any success as a happy bonus.
Myths
Haworthia needs full, direct sun all day like a desert cactus.
You can set this worry aside, because in the wild it lives sheltered in part shade among rocks and grasses rather than out in the blaze. Give it bright indirect light and it thrives, while harsh direct sun only scorches and discolors those pretty leaves.
Haworthia is a kind of aloe.
It is an easy mix-up, since the two were once grouped together and still share the Asphodelaceae family. Rest easy knowing haworthia stands as its own genus of small rosette succulents, quite separate from the true aloes.
