Euphorbia horrida is a striking and sculptural succulent cactus. Native to South Africa, this fascinating species forms compact, rounded columns covered in pronounced ridges lined with short spines. Its colouring ranges from blue-green to grey-green, sometimes developing a silvery bloom that enhances its rugged, desert-like charm. Over time, mature plants can form small clusters, creating an impressive architectural display that suits both modern and naturalistic settings.
Despite its fierce appearance, Euphorbia horrida is relatively easy to care for and makes a superb choice for collectors and houseplant enthusiasts alike. It thrives in bright, indirect to full sunlight and prefers a warm, well-ventilated position such as a sunny windowsill or conservatory. Use a free-draining cactus or succulent compost, and water sparingly, allowing the soil to dry completely between waterings. Overwatering should be avoided, as this can cause root rot. During the winter months, when the plant rests, watering should be reduced to a minimum.
In the growing season, Euphorbia horrida may produce small, yellow-green flowers near the tops of its ribs, adding a subtle yet beautiful detail. Though visually similar to true cacti, it belongs to the Euphorbia family and contains a milky sap typical of the genus, which should be handled with care as it can be irritant.
Ideal for garden centres and houseplant shops, Euphorbia horrida offers customers a distinctive, low-maintenance plant with a bold, sculptural presence that fits perfectly into contemporary plant collections and interior displays.
