About Stapelia variegata

Orbea variegata · also called starfish flower, toad plant · houseplant

Orbea variegata (long known as Stapelia variegata) is the most popular starfish flower, a tough South African stem succulent with flat, five-pointed, yellow flowers heavily mottled in maroon. Soft four-angled grey-green stems form low clumps. The blooms smell faintly of carrion to draw flies. Easy and forgiving, it needs only bright light, gritty soil, and a dry winter.

Mature size: Stems reach about 10-15 cm (4-6 in) tall, spreading to 30 cm (12 in) or more; the flat starfish flowers are typically 5-8 cm across.

Watch for — Stem rot: Overwatering or cold-wet soil causes soft, blackening stems. Cut out rot, let it callus, and re-root healthy stem pieces in dry gritty mix.

How to tell stapelia variegata needs repotting

Repotting on a calendar is less reliable than reading the plant. For stapelia variegata, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot stapelia variegata

Every 2–3 years, into bone-dry mix. Stapelia variegata's growth habit — low, clump-forming succulent with soft, four-angled, toothed grey-green stems that branch from the base and often sprawl into spreading mats. — sets the pace. Orbea variegata (long known as Stapelia variegata) is the most popular starfish flower, a tough South African stem succulent with flat, five-pointed, yellow flowers heavily mottled in maroon. Soft four-angled grey-green stems form low clumps. The blooms smell faintly of carrion to draw flies. Easy and forgiving, it needs only bright light, gritty soil, and a dry winter.

What size pot to step stapelia variegata up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Stapelia variegata stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot stapelia variegata

Spring or summer, while stapelia variegata is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting stapelia variegata

Repot dry. Do not water stapelia variegata for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty free-draining cactus and succulent mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set stapelia variegata at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep stapelia variegata completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for stapelia variegata

Stapelia variegata wants free-draining cactus and succulent mix. Use a gritty, fast-draining medium, cactus compost mixed with perlite, pumice, or coarse sand. A shallow, well-drained pot suits the spreading, shallow roots; avoid dense, moisture-retentive potting soils. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting stapelia variegata — frequently asked questions

How often should you repot stapelia variegata?

Every 2–3 years, into bone-dry mix for stapelia variegata. Repot stapelia variegata every 2–3 years into a snug pot of free-draining cactus and succulent mix, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does stapelia variegata need?

When is the best time of year to repot stapelia variegata?

Should you water stapelia variegata after repotting?

No — not straight away. Repot stapelia variegata into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise stapelia variegata after repotting?

Not immediately. Wait about 3 weeks after repotting stapelia variegata. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
