Decary's flamboyant
Decary's flamboyant (Delonix decaryi)
Delonix decaryi is a drought-deciduous Madagascan Delonix with a characterful swollen base or caudex, fine foliage, and cream-to-red flowers — a xerophytic trunk-and-base specimen for dry-tropical collector palettes, related to but visually distinct from common gulmohar (Delonix regia).

At a glance
- Botanical name
- Delonix decaryi
- Family
- Fabaceae
- Common names
- Decary's flamboyant, Madagascar flamboyant (collector)
- Origin
- South-western Madagascar
- Plant type
- Dry-deciduous caudex-base tree
- Mature height
- Often 5–10 m — smaller than gulmohar
- Trunk / form
- Swollen base/caudex with fine ferny foliage; cream and red flowers
- Crown spread
- Moderate open crown
- Growth rate
- Slow to moderate — caudex develops over years
- Light
- Full sun
- Water needs
- Xerophytic — rot if over-irrigated
- India climate suitability
- Dry tropical collector sites — arid resorts, xeric courts with drainage
- Cold/heat & salt/wind tolerance
- Heat- and drought-hardy; frost-sensitive; long bare season in dry climates
- Typical supply size
- Caudex-profile specimens 2–5 m [Unverified]
- Lead time (sourcing)
- [Unverified] collector nursery — rarely avenue stock
- Install considerations
- Swollen base drainage; long deciduous phase guest messaging
- Maintenance level
- Low — dry-season discipline and seasonal litter
- Cautions
- Long dry-deciduous bare period; rare; do not confuse with Delonix regia avenue plantings

Section
Where it's used in premium projects
Decary's flamboyant fits collector dry-garden briefs — private arid estates, boutique safari-lodge courts, and botanical collections where a swollen Delonix base replaces gulmohar's familiar umbrella crown. The caudex is the trunk story; flowers are cream-red accent, not scarlet avenue wash. Specify against Delonix floribunda when profuse bloom is the priority instead of base sculptural mass.
Section
Climate & site suitability in India
Dry tropical pads with free drainage — same philosophical siting as other xeric caudices. Long dry-deciduous bare seasons look stark on hotel arrivals unless lighting and messaging plan for leafless months. Humid coastal clay without rebuild fails swollen bases quickly.
Section
Sourcing & acclimatisation
Collector channels — verify caudex swell on photos, not juvenile whip stock. [Unverified: India-accessible decaryi holding.] Do not accept generic 'Madagascar flamboyant' labels that might be regia seedlings.
Section
Installation (pit, soil, drainage, bracing)
Swollen base sits above monsoon grade — raised planter or mound detail standard. Fine roots still need water to establish but caudex collar must dry between events. Light stake on windy arid drops until roots anchor.
Section
Establishment & AMC
Dry establishment protocol — sprinkler overspray on caudex is the failure mode. AMC documents bare-season appearance for owner expectations. Minimal crown prune — protect base silhouette over gulmohar-style umbrella shaping.

- How is Decary's flamboyant related to gulmohar?
- Same Delonix genus — decaryi is a smaller xeric species with swollen base and cream-red flowers, not the scarlet umbrella crown of Delonix regia.
- What defines the swollen base or caudex?
- Lower trunk flares into water-storing mass — the sculptural feature decaryi sells versus avenue gulmohar.
- How long is the dry-deciduous bare period?
- Extended in arid climates — programme lighting and guest communications; it is not a maintenance failure.
- Decaryi versus Delonix floribunda on the same pad?
- Decaryi emphasises caudex base; floribunda leans profuse flowering with swollen-trunk tendency — pick one story per court.
- What drainage prevents caudex rot?
- Raised planting, free-draining media, and no chronic irrigation at the swollen collar through monsoon.
- Are Madagascan Delonix imports quarantine-sensitive?
- Live plant imports require phytosanitary clearance — confirm species ID on paperwork matches decaryi, not regia (informational, not legal advice).
- How should decaryi BOQs be written?
- Include caudex photo verification, bare-season guest plan, dry AMC, and collector rarity premium — not gulmohar avenue rates.
