Harvest Tips
Baseball plants are ornamental specimens, not harvested for food or material. Seeds can be collected when capsules split open and dry on the plant (spring/summer). Collect immediately as seeds have short viability. Propagation via seeds is slow; offsets rarely produced.
Fun Facts
- 🌱 Euphorbia obesa is dioecious, meaning individual plants are either male or female. Only female plants produce seeds, making viable seed collection challenging for collectors.
- 🌱 The baseball plant was nearly extinct in its native South African habitat due to over-collection by enthusiasts, leading to its protection in the wild and establishment of cultivation programs.
- 🌱 Despite its succulent appearance, Euphorbia obesa is not closely related to other succulents like cacti or echeveria; it belongs to the Euphorbiaceae family and produces a toxic milky latex sap when damaged.
