🌿 Species guide
🌵 Euphorbia
🌿 In brief — Euphorbia (Candelabra tree)
Sizes: from H40 cm to over 1 m · Silhouette: vertical ribbed stems, candelabra form · Strength: graphic, sculptural, very low maintenance · Difficulty: very easy, ideal for beginners · Light: bright, tolerates full sun · Watering: rare, like a cactus
Euphorbia is a spectacular indoor plant with an architectural form: its vertical ribbed stems rise like a candelabra, creating a unique sculptural silhouette. Native to Africa, it stores the water in its fleshy stems like a cactus, making it one of the most resilient and easiest plants to care for. Bright, graphic, and nearly indestructible, it stands out as a statement piece in a contemporary interior. This guide covers available varieties, full care, and propagation by cuttings.
Botanical profile and history
The Euphorbia genus is one of the largest in the plant kingdom, with thousands of species worldwide. Species grown indoors, like Euphorbia trigona and Euphorbia acrurensis, originate from Africa, where they grow in hot, dry environments. Their succulent plant morphology — thick, ribbed stems capable of storing the water — is an adaptation to these arid climates.
A cactus look-alike
Euphorbia is often mistaken for a cactus, and for good reason: fleshy stems, upright silhouette, small spines along the edges. Yet botanically, they are two distinct families. This resemblance is a great example of convergence: two distant lineages adopting the same form to survive the same desert conditions.
An architectural plant
What makes Euphorbia popular in decoration is its candelabra shape: a central stem from which vertical branches extend, forming a geometric and sculptural structure. Few indoor plants offer such a graphic presence with so little care.
Euphorbia varieties
Indoor Euphorbias share the same minimalist care — what sets them apart is their silhouette and color. The full Euphorbia collection is available online.
Nicknamed “Cowboy Cactus” for its western silhouette, it raises thick, ribbed green columns, perfectly vertical. A sculptural piece that structures an interior and plays the graphic minimalism card.

The most iconic: its bright green triangular stems branch vertically into a true candelabra. Small leaves appear along the edges in full season. Easy growth and spectacular shape.
Discover the trigona →
The colored version of the trigona: its stems are tinted purple and dark red, even more intense in full light. Same candelabra shape, but with an added graphic and warm dimension.

| Variety | Silhouette | Color | Light | Ideal for |
|---|---|---|---|---|
| acrurensis | Straight columns | True green | Bright in full sun | Minimalist sculptural piece |
| trigona | Branched candelabra | Bright green | Bright in full sun | Classic graphic presence |
| trigona 'Rubra' | Branched candelabra | Green and purple | Bright (intensified color) | Colorful and warm effect |
Unsure between green and red? The red and green trigona duo combines both shades for a striking contrast.
Complete care
Light — as bright as possible
Euphorbia loves light. Place it in front of the brightest window in your home — it even tolerates a few hours of direct sun, which intensifies the purple hues of the 'Rubra'. In insufficient light, the stems become elongated and thinner as they seek light.
Watering — rare, like a cactus
This is the key point: Euphorbia stores water in its stems and fears excess moisture. Water only when the substrate is completely dry, about every 2 to 3 weeks in summer, and very little in winter (maximum once a month). When in doubt, do not water: it tolerates drought much better than excess water.
⚠️ Handling — irritating latex
Like all Euphorbias, the milky sap that flows when cut is irritating to the skin and eyes. Wear gloves when pruning or repotting, avoid any contact with the face, and wash your hands afterward.
Temperature and substrate
Euphorbia enjoys warmth (18 to 27 °C) and fears the cold: never expose it below 12 °C. Use a special cactus and succulent substrate, very well-draining, or a mix of potting soil + coarse sand + perlite. Drainage is vital to avoid root rot.
Repotting and fertilizing
Repot only every 2 to 3 years, in spring, in a pot just slightly larger. Its growth is slow to moderate. A diluted cactus fertilizer once a month from April to September is more than enough to support it.
- Maximum light — in front of the brightest window
- Water only when the substrate is completely dry
- Very little water in winter — once a month maximum
- Special cactus substrate, ultra-draining
- Gloves required for pruning — irritating latex
- Never below 12 °C — frost-sensitive plant
Pruning and propagation
Pruning to control height
Euphorbia can grow tall over the years. You can cut the tip of a stem to limit its height or encourage branching. Do this in spring or summer, with a clean, sharp tool — and always wear gloves.
Propagating a stem cutting
Each cut segment can become a new plant. The method:
- Cut a healthy stem with a clean knife, wearing gloves
- Rinse the base with water to stop the latex flow
- Let the cutting dry in open air for 5 to 7 days, until the cut heals
- Plant the cutting in slightly moist cactus substrate
- Wait for rooting without watering heavily — patience is key
💡 Healing tip
Never skip the drying step: planting a freshly cut cutting almost certainly causes rot. The cut must be dry and healed before planting.
Common problems and solutions
| Symptom | Likely cause | Solution |
|---|---|---|
| Soft, browned base | Excess water, rot | Stop watering, check drainage, propagate the healthy top if needed |
| Thin, stretched stems | Lack of light | Move to the brightest location |
| Yellowing stems | Excessive or cold watering | Let dry completely, keep away from cold |
| Leaning growth | Light coming from only one side | Turn the pot a quarter turn each week |
| Wrinkled, soft stems | Prolonged lack of water | Resume regular but moderate watering |
| White cottony spots | Mealybugs | Dab with 70° alcohol, isolate the plant |
Decoration and pairings
An architectural piece
Euphorbia is a statement plant: placed alone in a beautiful decorative pot, it is enough to structure a corner of a room. Its verticality makes it an excellent counterpoint to plants with soft, trailing foliage. It naturally finds its place among contemporary style indoor plants.
What to pair it with?
- Desert trio: Euphorbia + cacti + succulents — a coherent mineral corner to compose from the Cactus & succulents collection
- Shape contrast: the graphic verticality of Euphorbia against round or trailing foliage creates a strong visual balance
- Color duo: green trigona and purple 'Rubra' side by side, for a sculptural play of shades
Decorative pots and style
The green or purple stems of Euphorbia stand out beautifully on decorative pots with clean lines: raw concrete, matte ceramic, natural terracotta. Prefer stable and heavy containers, as large specimens can grow tall and need a good base.

Frequently asked questions
Water only when the substrate is completely dry, about every 2 to 3 weeks in summer and once a month maximum in winter. When in doubt, do not water: Euphorbia tolerates drought much better than excess water.
Yes, it is a full light plant: place it in front of the brightest window, it even tolerates a few hours of direct sun. In insufficient light, the stems become elongated and thin.
Cut a healthy stem with gloves, rinse the base, let the cut dry for 5 to 7 days, then plant the cutting in slightly moist cactus substrate without overwatering.
It is almost always excess water that causes rot. Stop watering, check the drainage, and if the base is affected, propagate the healthy upper part to save the plant.
Its growth is slow to moderate, but over the years it can exceed one meter in height. You can prune the tips of the stems in spring to control its height and encourage branching.
