Euphorbia Meloformis

The Euphorbia Meloformis is a striking succulent plant, highly prized by collectors for its original appearance resembling a small sculpted watermelon. Its round, ribbed form, sometimes striped with green and purple tones, makes it a true botanical curiosity.

This member of the large Euphorbiaceae family is often mistaken for a cactus, although it is not one. It is a succulent with an underground caudex and a globular body, which can sometimes produce discreet leaves or lateral offsets. Its growth is slow, but its graphic aesthetic remains consistent throughout the year, making it a perfect plant for pot cultivation, in bright indoor spaces or in a greenhouse.

Unlike other euphorbias with vertical growth, the Euphorbia Meloformis remains relatively compact, rarely exceeding 10–15 cm in height. Over time, it can form a small clump through offsets, offering a charming display of juxtaposed spheres, similar to a row of small melons.

The Euphorbia Meloformis is endemic to the Eastern Cape province of South Africa, a semi-arid region where it grows on rocky slopes exposed to the sun, in very mineral soil.
To thrive, the Euphorbia Meloformis requires good sun exposure:

🌞 Full sun or bright partial shade : Ideally 4 to 6 hours of direct sunlight per day.
Like any succulent euphorbia, it fears stagnant moisture:

🌱 Spring / Summer : Water moderately when the substrate is dry deep down.
🌞 Ideal growing temperature : 20 to 30°C

❄️ Minimum tolerance : down to 5°C if the soil is dry.
Well-drained soil is essential:

🪨 Recommended substrate : a mix of cactus potting soil with 50% pumice or pozzolana.
🌼 Appearance : small yellow to greenish flowers.
