Overview
Ever wonder where the name comes from? It's the way a central rosette, the hen, sits surrounded by a whole brood of little offsets, the chicks. It's an alpine succulent from the mountains of Europe, and its botanical name, Sempervivum, means always living, which pretty much sums up how stubbornly it hangs on. Folks used to plant it right on their roofs on purpose.
Here's the funny part: the very thing that makes it easy is what trips people up. It wants poor, gritty soil and next to no water, so all that usual houseplant fussing with regular watering and rich mix is exactly what rots it out. Treat it a little rough and it's happy as can be. Each rosette is monocarpic, which just means it flowers once, dies, and hands things off to its chicks, so the planting never really ends, even as the individual rosettes come and go.
Care
The short version: bright light, a fast-draining gritty mix, and water only once the soil has completely dried out. It barely needs feeding, and honestly it puts up with neglect way better than fussing.
Light
Give it full sun and you'll get the best color and the tightest rosettes. It'll take partial sun or a bit of light shade, but too little light stretches the rosettes out loose and washes out those reds and purples that make it fun to grow.
Water
Water sparingly, and only once the mix has dried out completely. It's an alpine succulent that stores its own water, so overwatering is honestly the quickest way to lose it. Ease way off in winter, when wet sitting around the crown just turns into rot.
Soil
Plant it in a gritty cactus or succulent mix that drains fast and never gets soggy. It's not picky about pH and it's happy anywhere from 6.0 to 8.0, and it actually likes lean, poor ground better than anything rich.
Temperature
Not many plants are this laid-back about temperature, handling anything from -40°F to 86°F (-40°C to 30°C). Cold? Doesn't faze it. Summer heat's fine too, as long as the drainage stays sharp.
Humidity
It likes things on the dry side and doesn't care one bit about low household humidity. Damp, still air is the real problem, since that's what brings on rot and rust with crowded rosettes.
Feeding
Feed it rarely, if you feed it at all. A dilute low-nitrogen succulent feed once or twice over spring and summer is plenty, and even that's optional. It grows in poor soil by nature, so it doesn't want to be pushed.
Pruning
There's barely anything to do. Once a hen flowers and dies back, just lift out the spent rosette and clear away any dried outer leaves, and the chicks around it will close the gap on their own.
Repotting
Repot every 2 to 3 years, or sooner if the offsets crowd up and spill over the pot edge. Keep an eye out for roots poking through the drainage holes or the mix drying out faster than it used to, then bump it up into fresh gritty mix.
Size & spacing
The rosette clumps stay low, hitting 6 to 12 inches (15 to 30 cm) tall and spreading 6 to 18 inches (15 to 45 cm) wide as the chicks multiply. Give a colony some room to creep and it'll slowly fill in the space.
Troubleshooting
Just about every hen and chicks problem circles back to the same thing, which is too much water. Get the drainage and the watering sorted and there's not a whole lot left to go sideways. Find your symptom below, then jump on it before rot works its way through the rosette.
A soft, blackening rosette that caves in at the middle
What you're looking at is crown and root rot, and it almost always means it got too much water or the mix just won't drain. So pull those mushy rosettes and toss them, then leave the watering can alone until everything dries out. Any firm chicks are still good, so pop them into fresh gritty mix that drains well and they'll keep going.
Fix:
- Remove and discard affected rosettes
- Withhold water and let the mix dry fully
- Salvage firm healthy offsets and replant in fresh gritty mix with sharp drainage
Orange-brown raised spots showing up on the leaves
That's rust, a fungus that moves in when plants stay damp and packed too tight. Pick off the spotted leaves and rosettes, and give the clump some breathing room so air can get through. Keep water off the leaves and split up a crowded colony, and you've basically got it beat.
Fix:
- Remove and dispose of affected leaves and rosettes
- Improve airflow and spacing
- Avoid wetting the foliage when watering
A rosette shoots up a stalk, flowers, then dies off
Nothing's actually wrong, since this is just the monocarpic life cycle doing its thing. Each hen blooms once and then goes, but she leaves a whole ring of chicks behind to take over. Want it tidy? Snip out the spent rosette and let the offsets fill in, or lift them and plant them somewhere new.
Fix:
- Remove the spent flowered rosette
- Allow surrounding offsets to fill the space
- Replant detached offsets if desired
Toxicity
Good news here: hen and chicks is non-toxic, full stop. The ASPCA lists Sempervivum with its safe succulents, and there's no harmful compound on record. So keep it around cats, dogs, and kids and don't give it a second thought, though it's still a plant on a shelf, not a snack.
Safe for
People · Cats · Dogs · Horses · Rabbits · Livestock · Birds
Cats None
Cats are totally fine around it, since there's no toxic compound on record. If a bored cat gnaws a rosette, the most you'll see is a bit of passing tummy upset.
Dogs None
Dogs can hang out near these succulents no problem. Sure, a dog that scarfs a big mouthful of any plant might have a loose day, but there's no actual poison here.
Horses None
Horses have nothing to worry about either, so a curious taste out in the pasture or from a planter won't do a thing.
Rabbits None
Rabbits do just fine near hen and chicks, and the fleshy leaves don't carry anything harmful. Even so, it's happier as a houseplant than as a regular green in the food bowl.
Livestock None
Cattle, goats, and sheep can graze it without any trouble, because there's no toxin in it to upset a ruminant stomach.
Birds None
Pet and backyard birds can peck away at the rosettes and be perfectly fine, since nothing in the leaves is poisonous to them.
People None
It's been grown on rooftops and windowsills forever, so it's no danger to people at all. There's no need to keep it away from curious kids.
Varieties
Mostly, hen and chicks vary by the color their rosettes turn as the season rolls on. A few named cultivars are handy to know if you've got a particular shade in mind.
Sempervivum tectorum 'Rubin'
You'll spot this one by its rosettes, which flush a deep ruby-red to purple that sticks around all season.
Sempervivum tectorum 'Sunset'
This one's foliage warms up to those glowing orange-red sunset tones as it gets older.
Sempervivum tectorum subsp. tectorum 'Triste'
Rather than anything flashy, this one settles into a muted, dull reddish-brown tint.
How to propagate
This has to be one of the easiest plants to multiply, and a lot of the time it just does the work for you by throwing out chicks. Want it faster? You can split a clump or sow seed instead.
Offsets & pupsEasy
Spring to early summer · 2-4 weeks to root
Pulling offsets is the easy route, and it's what most growers go with. Anytime from spring into early summer, just twist a rooted chick off the mother rosette and press it into gritty mix, and it'll take hold in about 2 to 4 weeks. Don't forget the monocarpic thing, either: the hen dies after flowering, and these chicks are exactly how the colony keeps itself going.
DivisionEasy
Spring · 2-4 weeks
Got a clump that's gotten crowded? Division is the way to go. In spring, lift the whole mat and gently pull it apart into single rooted rosettes, then replant each one. They'll settle in within about 2 to 4 weeks.
SeedModerate
Spring · Several months to a year
Seed is the slow road, and it's really only worth it if you want a bunch of plants at once. Sow in spring and settle in for the wait, because seedlings take several months to a year to add up to much, and named cultivars hardly ever come true from seed anyway.
Myths
The ASPCA Hens and Chickens listing proves Sempervivum tectorum was tested and cleared as pet-safe.
Here's the catch: that entry is actually Echeveria elegans, a tender Mexican succulent from a totally different genus. The cold-hardy Sempervivum, the real houseleek, shows up on its own on the ASPCA's non-toxic succulent list. They're both safe, just under separate listings.
Houseleeks have to come indoors for the winter.
Not even close, since these are some of the toughest succulents out there, rated RHS H7 and coming through cold way below freezing across USDA zones 3 to 8. They'll live outside all year, even where it gets brutal. It's the wet that gets them, not the cold, so the only real winter job is keeping the crowns out of soggy mix.
The whole plant is dying when the central rosette throws up a stalk and collapses.
Nope, just that one rosette is on its way out. Every hen is monocarpic and dies after it flowers, but it always leaves a ring of chicks behind to carry on. The colony keeps right on going through its offsets, and it often ends up looking fuller than before.
