Flowering tree
Flame tree (royal poinciana)
Delonix regia
Spreading flowering tree 8–12 m tall with a crown usually wider than tall, 12–18 m (UF/IFAS); Gardmi uses a 14 m crown. Surface roots lift paving, so keep it well away from buildings. Frost-tender (USDA 10b–11).
Planning parameters
Use these values as a practical planning envelope: they describe the adult plant, not the young seedling.
- Adult height
- 8-12 m
- Crown diameter
- 14 m
- Root zone
- 14 m
- Root type
- Wide shallow surface roots that can lift paving and crack thin slabs
- Recommended setback
- Keep at least 7 m from the house, pool and paving
- Growth rate
- Fast
- Hardiness
- USDA 10b–11 (damaged below about 0 °C)
- Crown density
- Medium, light filtered shade
Site requirements
These conditions decide whether the plant will establish well after planting.
- Light
- Full sun
- Watering
- Moderate; drought tolerant once established
- Soil type
- Most well-drained soils, including sandy
- Drainage
- Tolerates periodic drought; avoid waterlogging
- Soil pH
- Acidic to alkaline
Root system and placement
Plan a root zone of about 14 m diameter
Garden role and season
These fields help choose the plant by composition, privacy, flowering and year-round value.
- Form
- Very wide umbrella-shaped tree, usually broader than tall
- Foliage
- Fine feathery bipinnate leaves; sheds them in the dry season
- Season
- Early summer bloom
- Bloom
- Masses of scarlet to orange flowers in late spring and early summer
- Fruit
- Long flat woody pods up to 50 cm; messy litter
- Garden use
- Shade and flowering specimen for large gardens; one tree shades a whole terrace
Care and risks
This is the practical part for future maintenance and safe placement on the plot.
- Maintenance
- Water young trees; prune early to one strong trunk with well-spaced branches
- Pruning
- Prune while young to avoid weak narrow forks
- Risks
- Weak wood — limbs break in storms; surface roots and pods; do not plant near foundations
