Euphorbia Obesa
Euphorbia obesa
📖 About this plant
Euphorbia obesa, commonly called the Baseball Plant, is one of the most fascinating and highly sought-after succulents in the world. Its perfectly spherical, grey-green body with subtle vertical ribs resembles a small baseball or sea urchin, making it a striking conversation piece. Native to a tiny region of South Africa, it’s endangered in the wild due to over-collection. Unlike true cacti, it produces no spines but contains toxic latex sap. As a dioecious species, it requires both male and female plants for seed production, making propagation extremely challenging and contributing to its rarity and collector value.
🧑🌾 Care requirements

18-30°C (65-85°F)
Very gritty, well-draining mix with 60-70% mineral components (pumice, perlite, gravel)
Diluted succulent fertilizer once in spring and once in summer only

🛡️ Health & Safety
TOXIC — latex sap is a severe irritant to skin, eyes, and mucous membranes; causes temporary blindness if contact with eyes; keep away from children and pets
Common issues
- Rotting from overwatering (most common cause of death), etiolation (stretching) in low light, latex sap irritation during handling, sunburn from sudden exposure to intense sun, very slow growth can concern new owners
💡 Care tips
- Never allow water to sit in the crown — water from below or around the base. Always wear gloves when handling due to the toxic latex sap. Provide the grittiest soil possible — mineral-heavy mixes work best. This is a long-term investment plant that grows extremely slowly but can live for decades. A deep pot accommodates the taproot. It's a threatened species in the wild — always purchase from reputable cultivated sources.
