Euphorbia Obesa

The Euphorbia Obesa, often nicknamed the "baseball plant" or "fat cactus", is an extremely original succulent plant that appeals to succulent lovers thanks to its unique spherical appearance and ease of cultivation. Native to South Africa, more precisely the semi-desert regions of the Cape, this fascinating specimen belongs to the Euphorbiaceae family — and not to the Cactaceae, despite its resemblance to some globular cacti.

This small botanical gem presents an almost perfect spherical shape when young, gradually becoming cylindrical with age. Its surface is marked with vertical lines often adorned with small areoles or darker markings. It can display shades ranging from dark green to gray-green, sometimes punctuated with reddish hues depending on sun exposure.

One of the most charming aspects of the Euphorbia Obesa is its compact nature: it generally does not exceed 20 cm in height with a maximum diameter of 10 cm, making it an ideal plant for small spaces, modern interiors, or minimalist compositions. It is a slow-growing plant, but with strong ornamental value.

The Euphorbia Obesa grows naturally in the semi-arid regions of the Cape Province, in rocky, well-drained soils under a dry and hot climate. In the wild, it is now threatened by overexploitation and is listed among protected species.

To thrive, the Euphorbia Obesa needs light, without excess:

🌤️ Ideal exposure: bright light without prolonged direct sunlight, especially in summer. An east- or west-facing window is ideal.

☀️ Tip: a little direct morning sun can enhance its beautiful color nuances, but beware of burns in summer.

Like most succulents, watering of the Euphorbia Obesa must be moderate:

🌱 Spring / Summer: water every 2 to 3 weeks, only when the substrate is completely dry.

🍂 Autumn / Winter: almost no watering. During dormancy, excess moisture can be fatal.

⚠️ Important: always use a well-draining cactus soil and a pot with drainage holes to prevent root rot.

The Euphorbia Obesa is a heat-loving plant:

🌡️ Ideal temperature: between 20°C and 30°C during the growing season.

❄️ Cold tolerance: not below 10°C. It does not tolerate frost or prolonged humidity. Bring it indoors at the beginning of autumn.

🏠 Winter advice: place it in a bright, frost-free room, with little or no watering.

An adapted substrate is crucial to avoid rot risks:

🪨 Recommended substrate: mix cactus soil with 50% pumice or pozzolana for optimal drainage.

The flowering of the Euphorbia Obesa is as discreet as it is fascinating:

🌸 Season: late spring to summer, depending on maturity.

🎨 Color: pale green to yellowish.

🕑 Duration: a few days.

💡 Note: only a well-established adult plant, correctly exposed and having undergone slight water stress, can flower.
