About Hens and chicks

Sempervivum tectorum · also called Hens and chicks, Common houseleek · houseplant

Hens and chicks is a hardy alpine succulent that forms tight rosettes (the "hen") ringed by offset pups (the "chicks"). Its one non-negotiable need is sharp drainage: it stores water in its fleshy leaves and rots quickly in soggy compost, so treat it lean, sunny and on the dry side.

Mature size: Rosettes stay low, to about 10cm (4in) tall, spreading 0.1-0.5m (4-20in) wide as a colony; flowering stems reach 20-30cm. Takes around 5-10 years to fill its ultimate spread.

Indoor size vs how big it gets in the wild

Hens and chicks is a tree at heart. Indoors a pot and your ceiling keep it to rosettes stay low, to about 10cm (4in) tall, spreading 0.1-0.5m (4-20in) wide as a colony, but in the ground it is a different scale of plant entirely (flowering stems reach 20-30cm. takes around 5-10 years to fill its ultimate spread.). Indoors and in a pot, expect rosettes stay low, to about 10cm (4in) tall, spreading 0.1-0.5m (4-20in) wide as a colony. In the ground with no restriction it is a completely different plant — flowering stems reach 20-30cm. takes around 5-10 years to fill its ultimate spread. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Growth rate and years to mature

Hens and chicks is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: feeds very lightly. a slow-release fertiliser mixed into the compost lasts months; otherwise a monthly weak general liquid feed during spring and summer growth is plenty. do not feed in winter. plants grown in open garden soil usually need no feeding at all, and over-feeding causes soft, rot-prone growth.

Want this turned into the right next pot at the right moment? The pot size calculator and the hens and chicks repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast hens and chicks grows.

How to keep hens and chicks smaller

You are not stuck with the maximum size. For hens and chicks specifically, these are the levers, in order of impact:

The decisive tool is the secateurs: hens and chicks can be topped (cut the main growing tip) to cap its height and force a bushier, shorter shape.
Keeping it deliberately pot-bound in a snug container slows the whole plant and limits ultimate size.
Prune in spring so it heals fast; remove the tallest leader back to a node to reset the height.
Expect to top or hard-prune it every year or two — left alone it heads for the ceiling.

The keep-it-smaller method, step by step

Pick the new height. Decide how tall you want hens and chicks and find a leaf node or branch point just below that.
Top the main stem. Cut the main growing tip cleanly just above that node in spring; this permanently caps the height and forces side branches.
Keep the pot snug. Avoid jumping to a much bigger pot — a slightly restricted rootball keeps the whole plant smaller.
Maintain the shape. Prune back the tallest new leaders each spring to hold it at the height you chose.

How to grow hens and chicks bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for hens and chicks the accelerators are:

It already wants the bright light it needs; warmth, a yearly pot-up and spring-summer feed are the accelerators.
Pot up a size every year or two while young; restricted roots are the main thing holding height back.
Feed regularly through the growing season and keep it warm — height comes from sustained good conditions.

Light is almost always the ceiling. The hens and chicks light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When hens and chicks outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for hens and chicks:

The top leaves pressing against or bent by the ceiling — the classic "this is now too tall indoors" sign.
It has to be moved away from a light source it has literally outgrown.
Roots filling the largest pot you can reasonably keep indoors — at that point it is top-or-prune or move it outside (if hardy).

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the hens and chicks repotting guide. If you want more of this plant instead of a bigger one, the hens and chicks propagation guide turns prunings into new plants.

Hens and chicks size — frequently asked questions

How big does hens and chicks get?

Hens and chicks reaches rosettes stay low, to about 10cm (4in) tall, spreading 0.1-0.5m (4-20in) wide as a colony when grown indoors, and far larger where it grows unrestricted (flowering stems reach 20-30cm. takes around 5-10 years to fill its ultimate spread.). It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Is hens and chicks slow or fast growing?

Hens and chicks is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Hens and chicks is a tree at heart. Indoors a pot and your ceiling keep it to rosettes stay low, to about 10cm (4in) tall, spreading 0.1-0.5m (4-20in) wide as a colony, but in the ground it is a different scale of plant entirely (flowering stems reach 20-30cm. takes around 5-10 years to fill its ultimate spread.).

How long does hens and chicks take to reach full size?

Roughly three to six years to reach mature indoor size, gaining a steady amount each growing season. Light, pot size and feeding move that timeline more than anything else.
