Euphorbia turbiniformis is an extraordinary miniature Euphorbia native to Somalia, prized for its compact, flattened body, intricate surface patterning, and almost stone-like appearance. Even among collectors of unusual Euphorbias, it is a distinctive species: slow-growing, remarkably small, and sufficiently challenging in cultivation that specimens are frequently grafted onto more vigorous rootstocks.

And then there is this specimen.

Rather than being grafted onto the conventional upright green Euphorbia stock typically used for E. turbiniformis, this plant has been grafted onto an unidentified caudiciform Euphorbia rootstock with an enormous, exposed, multi-lobed storage organ.

The result is one of the strangest E. turbiniformis specimens we have encountered.

The turbiniformis scion itself measures approximately 1.5" across and shows proliferating growth across its beautifully patterned surface. Beneath it sits the massive pale caudex—an entirely separate Euphorbia whose identity is unknown and whose extraordinary swollen form has become as much a part of the specimen as the rare plant grafted above it.

Care Instructions

☀️ Light
Provide very bright light with some direct sun. Strong light encourages compact growth and good coloration, but acclimate the plant gradually following shipping or any significant change in growing conditions.

💧 Water
Water carefully during active growth, allowing the substrate to dry thoroughly between waterings. Both the valuable scion and the unusual caudiciform rootstock make conservative watering particularly important. Keep substantially drier during cool or dormant periods.

🪨 Soil
Use an exceptionally fast-draining, mineral-rich succulent mix. Pumice, lava rock, coarse grit, decomposed granite, and similar inorganic materials are excellent choices. Avoid rich soil that retains moisture for prolonged periods.

🌡️ Temperature
This is a warmth-loving specimen and should be protected from frost. Avoid prolonged exposure to cold, particularly when the substrate is damp.

🌬️ Humidity
Prefers dry conditions with excellent airflow. In humid environments, careful watering and an extremely porous substrate become especially important.

📈 Growth Habit
Euphorbia turbiniformis normally remains remarkably compact, producing a small flattened to rounded body. This grafted specimen shows multiple developing growth points, creating an increasingly complex upper surface rather than the simple solitary form often associated with the species.

The unidentified rootstock follows an entirely different strategy, storing resources within its enormous swollen caudex.

✍️ Special Note
The spectacular caudex beneath this plant does not belong to Euphorbia turbiniformis.

This is an intentional graft involving two different Euphorbias: E. turbiniformis forms the green scion above, while an unidentified caudiciform Euphorbia forms the massive rootstock below.

We do not know the species used for the rootstock and would rather leave its identity honestly unresolved than speculate.

The caudex has been intentionally displayed above the soil line in our photographs so that its extraordinary architecture can be fully appreciated. When repotting, take care not to bury the graft union.

Like other members of the genus, both portions of this plant may produce irritating and toxic milky latex sap if damaged. Avoid contact with skin and especially eyes, and keep the plant away from children and pets.

Natural scars, corking, surface marks, and irregularities are expected on an established caudiciform plant. Please review all photographs carefully, as you will receive the exact specimen shown.

Why It Stands Out

• Rare Euphorbia turbiniformis
• Extraordinary caudiciform Euphorbia rootstock
• Approximately 3" wide × 2.5" tall above the soil line
• Turbiniformis scion approximately 1.5" wide
• Multiple developing growth points on the scion
• Massive exposed multi-lobed caudex
• Rootstock itself becomes part of the specimen
• Extremely unusual alternative to a conventional columnar graft
• Two dramatically different Euphorbia growth strategies in one plant
• A genuinely bizarre collector specimen
• We have never offered another quite like it
• The exact specimen shown here

Collector Notes

Most grafts are designed to disappear.

The rootstock has a job: establish a vigorous root system, supply water and nutrients, and support a slower or more difficult plant growing above it. Ideally, the collector eventually pays very little attention to what is underneath.

This plant refuses to cooperate with that arrangement.

At the top is Euphorbia turbiniformis, an extraordinary miniature species from Somalia. On its own roots, the species produces a relatively small body with a thickened, turnip-like form below ground, but nothing resembling the enormous exposed caudex seen here.

That belongs to somebody else.

At some point, a grower selected an unidentified caudiciform Euphorbia as the rootstock, removed its original upper growth, and grafted E. turbiniformis onto it.

The choice is fascinating because a caudiciform plant solves the problem of survival very differently from turbiniformis.

A caudex is essentially biological storage architecture—a swollen stem, root, or combination of structures capable of holding reserves that allow a plant to endure long periods when water and favorable growing conditions disappear.

In this specimen, that architecture has become enormous in relation to the scion.

The pale rootstock swells outward into a collection of massive rounded lobes. Above them, connected by a surprisingly narrow neck, sits the tiny green turbiniformis.

The proportions are almost comical.

And that is precisely what makes the specimen remarkable.

Conventional E. turbiniformis grafts are frequently supported by upright green stocks whose purpose is obvious and whose appearance is secondary. With this plant, the rootstock has become part of the composition.

Two plants have effectively been turned into one collector object.

The contrast is especially striking because E. turbiniformis itself is so restrained. Its surface is divided into intricate geometric structures, with tiny growth points and subtle coloration compressed into an exceptionally small body.

Underneath it is this enormous, primitive-looking storage organ.

Intricate above. Monumental below.

There is another curiosity here as well.

The turbiniformis scion is no longer presenting as one simple solitary button. Multiple areas of active growth are developing across it, giving the upper plant an increasingly proliferating, irregular form. Given time, those growth points may further alter the balance between the tiny scion and its disproportionately massive foundation.

We have deliberately not assigned a species name to the rootstock. Once the foliage and original stems of a caudiciform Euphorbia have been removed, many of the botanical characteristics necessary for confident identification disappear with them. Several species could potentially produce swollen structures of this general kind, but possibility is not identification.

What we can identify is the plant above it.

What we can see is the extraordinary plant beneath it.

And what somebody created by putting the two together is far more interesting than pretending we know something we don't.

At approximately 3" across, the entire specimen can nearly disappear into the palm of a hand.

Yet within those three inches are two completely different survival strategies, two different plant architectures, an intentional graft, an unidentified caudex, and one of the strangest little Euphorbia turbiniformis specimens we have ever encountered.

Sometimes the graft is merely how a plant is grown.

On this one, the graft is the story.
