About Carrion Flower (Stapelia gigantea)

Stapelia gigantea · also called Carrion flower, Starfish flower · flowering

Stapelia gigantea, the carrion or starfish flower, is a clumping South African stem succulent famous for giant star-shaped blooms that smell of rotting meat to lure pollinating flies. Give it full sun to bright light, gritty fast-draining soil, and sparing water. ASPCA lists no toxic Stapelia; treat as low-risk but vet-verify.

Mature size: Stems reach about 20-30 cm (8-12 in) tall, spreading into a clump 30-60 cm (1-2 ft) or wider over time. Star-shaped flowers are enormous for the plant, up to 25-40 cm (10-16 in) across.

Indoor size vs how big it gets in the wild

Carrion Flower (Stapelia gigantea) 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 stems reach about 20-30 cm (8-12 in) tall, spreading into a clump 30-60 cm (1-2 ft) or wider over time. star-shaped flowers are enormous for the plant, up to 25-40 cm (10-16 in) across.. 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

Carrion Flower (Stapelia gigantea) 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: feed lightly during the spring-to-early-autumn growing season only. use a balanced or low-nitrogen, high-potassium succulent/cactus fertiliser diluted to half strength roughly once a month. a higher-potassium feed encourages flowering. do not fertilise in winter dormancy, and never overfeed, as excess nitrogen produces soft, rot-prone stems and few blooms.

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

How to keep carrion flower (stapelia gigantea) smaller

You are not stuck with the maximum size. For carrion flower (stapelia gigantea) specifically, these are the levers, in order of impact:

Divide the clump every year or two — splitting carrion flower (stapelia gigantea) 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 carrion flower (stapelia gigantea) 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 carrion flower (stapelia gigantea) bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for carrion flower (stapelia gigantea) 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 carrion flower (stapelia gigantea) light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When carrion flower (stapelia gigantea) outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for carrion flower (stapelia gigantea):

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 carrion flower (stapelia gigantea) repotting guide. If you want more of this plant instead of a bigger one, the carrion flower (stapelia gigantea) propagation guide turns prunings into new plants.

Carrion Flower (Stapelia gigantea) size — frequently asked questions

How big does carrion flower (stapelia gigantea) get?

Carrion Flower (Stapelia gigantea) reaches stems reach about 20-30 cm (8-12 in) tall, spreading into a clump 30-60 cm (1-2 ft) or wider over time. star-shaped flowers are enormous for the plant, up to 25-40 cm (10-16 in) across. 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 carrion flower (stapelia gigantea) slow or fast growing?

Carrion Flower (Stapelia gigantea) is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Carrion Flower (Stapelia gigantea) 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 carrion flower (stapelia gigantea) 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.
