Baseball Plant (Euphorbia obesa)

Euphorbia obesa

Baseball Plant (Euphorbia obesa)

Endemic to the Great Karoo region of South Africa, Euphorbia obesa is a spineless, spherical succulent exhibiting exquisite geometric symmetry. It is a strictly dioecious species that matures from a solitary ball-shaped habit into a cylindrical columnar form accented by fine, tartan-like striations. Highly prized in cultivation, wild populations remain protected under CITES Appendix II due to historical overcollection.

📋 Core Botanical Care Parameters

☀️ Light Requirements

Requires full sun to very bright, lightly filtered light; insufficient illumination triggers unsightly etiolation and loss of its symmetrical spherical form.

💧 Watering Frequency

Utilize a strict soak-and-dry protocol; allow the entire substrate profile to dry out completely between waterings, and withhold water almost entirely during winter dormancy.

🏺 Soil Mix

70% coarse mineral grit (pumice, crushed lava rock, and coarse sand) + 30% organic cactus peat for rapid and flawless drainage.

❄️ Cold Tolerance

-2°C (USDA Zone 9b); can briefly tolerate mild frosts if kept strictly dry, but thrives best overwintered around 8-12°C.

🌱 Propagation Method

Almost exclusively propagated by seed (dioecious species requiring both a male and female specimen for pollination); very rarely propagated via offsets if any spontaneously emerge.

⚠️ Toxicity Warning

This plant contains toxic sap/compounds. Keep out of reach of cats and dogs.
