Euphorbia Stellispina

The Euphorbia Stellispina is a spectacular succulent native to southern Africa, prized for its spiny stems and dense, bristling shrub-like appearance. Its name “stellispina” refers to its formidable star-shaped spines arranged at the top of each node, giving the plant a defensive yet highly graphic look. Its compact, almost architectural habit makes it a remarkable euphorbia for lovers of sculptural plants.

Each stem is segmented, upright or spreading, often bluish-green or greyish in tone. Over time, the Euphorbia Stellispina can form a small shrub 30 to 50 cm tall, highly branched and capable of producing a true tangle of star-shaped spines. Although slow growing, it is easy to maintain and extremely drought resistant. It is suitable both for pot cultivation and dry gardens in mild climates.

In the wild, the Euphorbia Stellispina grows on arid soils, often rocky or sandy, in full sun in the semi-desert regions of the Northern Cape and Namaqualand. It blends among rocks and xerophytic shrubs, taking advantage of any available moisture thanks to its efficient root system and succulent tissues.
To maintain its compact habit and beautiful coloration:

🌞 Full sun or intense light: It thrives in very bright exposure, even outdoors in summer.

⚠️ Direct sun: It tolerates it very well, but gradual acclimation in spring is always recommended.
This species tolerates drought very well, provided drainage is good:

💧 Spring / summer: Water every 15 to 25 days.

❄️ Winter: Almost complete suspension of watering, especially during vegetative rest.
Robust, the Euphorbia Stellispina prefers warm climates:

🌡️ Ideal: 20 to 30 °C.

❄️ Lower limit: 5 °C if soil is dry, but it fears prolonged frost.
🪨 A very well-draining soil is absolutely essential:

Mix cactus substrate + 50% perlite, finished with a layer of pumice stone to protect the collar and enhance decorative mineral effect.
Discreet but intriguing, flowering deserves attention:

🌸 Period: Spring or early summer.

🟡 Flowers: Small greenish or yellowish cyathia appearing at stem axils.

💡 Feature: Not showy, but a sign of a healthy plant.
