About Pig's Ear

Cotyledon orbiculata · also called Pig's Ear, Round-Leafed Navel-Wort · houseplant

Cotyledon orbiculata is a robust South African succulent producing thick, powdery grey-green to cream-edged rounded leaves and attractive tubular orange-red flowers in summer. It forms a small shrubby plant and tolerates periods of drought. The ASPCA lists Cotyledon as toxic to cats and dogs.

Mature size: 30-60 cm tall and wide indoors

Watch for — Aphids: Can infest new soft growth and flower stems. Remove by hand or with a gentle insecticidal soap spray.

Indoor size vs how big it gets in the wild

Pig's Ear stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward. Indoors and in a pot, expect 30-60 cm tall and wide indoors. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Growth rate and years to mature

Pig's Ear 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: apply a diluted succulent fertiliser (half-strength) once a month during spring and summer. avoid nitrogen-heavy feeds, which promote overly soft growth at the expense of the powdery leaf texture.

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

How to keep pig's ear smaller

You are not stuck with the maximum size. For pig's ear specifically, these are the levers, in order of impact:

Divide the clump every year or two — splitting pig's ear is the main way to control its spread and refresh it.
Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump.
Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

The keep-it-smaller method, step by step

Lift the whole plant. Slide pig's ear out of its pot in spring when the clump has filled it.
Split the clump. Tease or cut the rootball into two or more sections, each with healthy roots and growth.
Repot one division. Put a single division back in the original pot to reset it to a smaller size; pot or give away the rest.
Remove offsets as they form. Through the year, detach new runners or pups to stop it spreading again.

How to grow pig's ear bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for pig's ear the accelerators are:

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger.
Good light plus regular feeding maximises offset and runner production.
Leave plantlets and offsets attached and feed through the growing season for the fastest spread.

Light is almost always the ceiling. The pig's ear light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When pig's ear outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for pig's ear:

The clump bulging over the pot rim or splitting the pot — the cue to divide, not to find a bigger room.
A dense centre that goes bare or tired while the edges keep spreading.
Runners or offsets escaping across the shelf or into neighbouring pots.

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

Pig's Ear size — frequently asked questions

How big does pig's ear get?

Pig's Ear reaches 30-60 cm tall and wide indoors when grown indoors. Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Is pig's ear slow or fast growing?

Pig's Ear is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Pig's Ear stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward.

How long does pig's ear 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.

How do I keep pig's ear smaller?

Divide the clump every year or two — splitting pig's ear is the main way to control its spread and refresh it. Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump. Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

How can I make pig's ear grow bigger or faster?

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger. Good light plus regular feeding maximises offset and runner production. Leave plantlets and offsets attached and feed through the growing season for the fastest spread.
