🔺 Crystalline geometry: clean five-angled edges on every stem.
🌵 Cactus-like look without demanding care.
💪 Tolerant of heat and drought — ideal for beginners.
Ideal uses
🏠 Bright windowsills, shelves and minimal compositions.
🪴 Shallow pots with mineral substrate and fine gravel topdressing.
🌿 Combinations with Haworthia, small Crassula and lithops.
Where to place it
Full sun or a very bright position with strong diffuse light. Pot with a drainage hole and a clearly free-draining, mineral mix; water sparingly, only when the substrate has completely dried out.
Planting companions
Dwarf Gasteria — contrast between broad and narrow textures.
Crassula perforata — geometric harmony in height.
Haworthiopsis attenuata — striped pattern next to the pentagonal ridges.
Variety origin click to read
Taxonomic history: The name Euphorbia pentagona is attributed to Haworth (Haw.) and carries the note non L. to distinguish it from a homonym described by Linnaeus. In cultivation it is used for a dwarf, five-angled Euphorbia with fleshy stems.
Habitat & distribution: Of South African origin, found in dry, rocky or sandy substrates with excellent drainage. Often in positions with full sun, where the stems stay compact and strongly angular.
Naming (etymology):pentagona = “five-angled”; it refers to the characteristic five-sided cross section of the stems and their prominent ridges.
Ecology & biology: A succulent with reduced/short-lived leaves; the stems take over most of the photosynthetic function. The cyathia are small and greenish; the white, milky latex has irritating properties.
Related species & distinction: It can be confused with other five- or multi-angled Euphorbia species (e.g. E. enopla, E. mammillaris when young). E. pentagona maintains consistently five clear ridges and a more regular geometry, with finer, more discreet “spines” along the angles.
Propagation & stability: Propagated by stem cuttings and offsets; cuts are left to callous so that latex flow stops before planting. In cultivation it forms stable, dense clumps.
Conservation status & threats: Wild populations are affected by habitat loss and collection from the wild; always prefer nursery-propagated plants.
1) Substrate: Mineral cactus mix (60–70% pumice/perlite/coarse sand + 30–40% poor organic base). Shallow pot with drainage hole.
2) Watering: Rare — only when the substrate is completely dry. Avoid water sitting in the saucer; excess water quickly leads to rot.
3) Light/Temperature: Full sun or a very bright position; 12–30°C. Below 10–12°C, keep absolutely dry and protected from rain and frost.

🌡️ Temperature
12–30°C • protect from frost
🧪 Toxicity
Caution: irritating white latex — keep away from children and pets and avoid contact with skin and eyes.
💡 Tip: Water around the edge of the pot and avoid soaking the stem base — it significantly reduces the risk of rot.
🤔 Did you know? The “spines” on many Euphorbia species are modified tissues — they are not true thorns like those on cacti.
Why you’ll love it info
🔺 Geometric, clean design that fits perfectly in minimal spaces.
🌞 Loves bright light — it looks best in sunny spots.
🪴 Forms dense clumps over time, adding volume and rhythm.
🧠 Greenleaf for nerds — scientific facts no one asked for geek
🔬 Stems with a five-sided cross section — fleshy and photosynthetic.
🧪 Latex containing irritating compounds; avoid contact with skin and eyes.
🧬 Propagation via cuttings and offsets (always let cuts dry and callous first).
🌿 In full sun it keeps a more compact, sharper geometry.
How much light does it need? light
Full sun or very bright indirect light. Indoors, place as close as possible to a south- or west-facing window.
How often do I water it? watering
Very rarely; water only when the substrate has dried out completely, even in depth.
What substrate does it prefer? soil
A sharply draining cactus mix (pumice/perlite/coarse sand) with just a small amount of organic matter.
Is it cold hardy? cold
It does best above 10–12°C. If temperatures drop, keep the plant completely dry and sheltered from frost.
🔎 Note: Due to the natural variability of plants, the plant you receive may differ slightly from the one in the photo. Form, size and colouring depend on the season, growing conditions and the nature of each plant.
Euphorbia pentagona 12cm Care & Tips
We take care of the packaging!
With specially designed boxes, we ensure that the plants will reach you intact, no matter what they encounter on the way!
All plants in 3L pots or larger are placed in individual boxes that secure the plant at the base of the pot, preventing it from tipping over.
The cardboard used for the boxes is specially made to provide resistance to potential impacts during transport.
