About Delonix Decaryi

Native to the dry forests of southwestern Madagascar, Delonix decaryi belongs to the Fabaceae family and is closely related to the famous Delonix regia (Royal Poinciana). Unlike its larger cousin, this compact species develops a remarkable caudiciform base – a water-storing, bottle-shaped trunk that makes it a prized specimen for:

• Bonsai enthusiasts seeking unique material
• Caudiciform collectors building rare plant collections
• Succulent gardeners looking for architectural specimens
• Dry-climate landscaping in frost-free regions

Distinctive Features

✓ Sculptural caudiciform trunk that thickens with age
✓ Feathery, fern-like foliage with fine bipinnate leaves
✓ Rare flowering – produces clusters of pale yellow to cream flowers
✓ Compact growth – ideal for container cultivation
✓ Drought-tolerant – perfect for water-wise gardens
✓ Madagascar endemic – true collector's rarity

Bonsai Potential
