Euphorbia antiquorum (WA Prohibited)

Euphorbia antiquorum is a distinctive tree-form succulent native to South Asia, prized for its broad winged stems, architectural branching habit, and unique appearance. Mature plants develop into impressive candelabra-shaped specimens, while younger plants display broad green ribs edged with small spines and seasonal leaves.

This species has been cultivated for centuries and remains one of the most recognisable of the large succulent euphorbias. Easy to grow and highly drought tolerant, it makes an outstanding specimen plant for collectors of unusual succulents.
