Fun Facts
- 🌱 Pachypodium bispinosum is called 'Elephant's Trunk' because its swollen caudex resembles an elephant's leg; the name 'bispinosum' refers to the two spines typically found at the base of each leaf.
- 🌱 This plant can live for several decades in cultivation and is extremely slow-growing, with some specimens taking 10+ years to reach substantial size, making them long-term investment plants for collectors.
- 🌱 In its native habitat of South Africa, Pachypodium bispinosum is adapted to extreme drought and survives by storing water and nutrients in its massive caudex, which can become quite large relative to the sparse foliage above it.
