About Delonix regia – Flame Tree / Poinciana

Delonix regia, commonly known as Flame Tree or Poinciana, is one of the most visually spectacular flowering trees in tropical and subtropical climates. It is prized for its fiery scarlet to orange-red flowers, wide-spreading umbrella-like canopy, and finely divided fern-like foliage.

Reaching 8–12 metres in height and 10–15 metres wide, it develops a strong central trunk with a broad, flat crown — providing excellent summer shade. Flowering occurs in late spring to mid-summer, often when the tree is fully leafed, creating a dramatic seasonal display.

They look excellent when used as a feature tree in large open lawns, civic plantings, or tropical gardens where canopy space allows. This species thrives in full sun, requires free-draining soil, and performs best in frost-free locations. Drought-tolerant once established, it is low maintenance and offers unmatched seasonal colour and structural form.

Planting, Spacing & Care

Choose a full sun position with room for mature spread
Plant in well-draining soil — avoid low-lying or boggy sites
Stake young trees for support and to encourage upright growth
Backfill with native soil and water in well after planting
Apply mulch around base, keeping it clear of the trunk

Feature Planting: Space 10 – 12 m apart
Shade Canopy: Space 8 – 10 m apart
Avenue Planting: Space 10 m apart for open-formal layout

Water deeply twice weekly during establishment (first 12–18 months)
Reduce watering once mature; drought-tolerant after establishment
Fertilise in spring with a slow-release fertiliser for best flowering

Performs best in sandy or loamy soils with excellent drainage
Avoid clay or waterlogged soils — root rot risk
Prefers neutral to slightly acidic soil but is adaptable if well-drained
