Cassia fistula
Cassia fistula supplied from Thailand for landscape projects for landscape projects in the Gulf and Asia. Mature height, calliper and root-ball sizes listed.
Golden shower tree · Fabaceae · Deciduous flowering tree
Thailand’s national tree, and the strongest ornamental in our range for hot, dry climates. In flower it carries long pendulous racemes of clear yellow across a bare or lightly leafed crown, which is why it is used where a scheme needs one moment of colour rather than continuous cover.
Specification
| Mature height | 10–15 m |
|---|---|
| Crown spread | 8–12 m (indicative) |
| Caliper range supplied | 5–22 cm standard, measured 1 m above soil level. Larger by arrangement. |
| Root-ball diameter | 80–140 cm (indicative) |
| Growth rate | Moderate |
| Habit | Deciduous — briefly leafless before flowering |
| Flowering | Pendulous yellow racemes, 30–60 cm, late dry season |
Landscape use
Boulevard and entrance planting, park groupings, courtyard and villa gardens. Best used in groups or repeated along an avenue, where the simultaneous flowering reads as a single event.
The flower fall is part of the effect — a carpet of yellow beneath the tree. It shows to best advantage set back a little from pools, seating and parking, over planting or lawn.
Site tolerance
| Drought | High once established |
|---|---|
| Salinity | Low to moderate (indicative) |
| Wind | Moderate — branches are brittle when young |
| Soil | Well-drained; tolerates poor and sandy soils. Dislikes waterlogging. |
| Heat | High — flowers most reliably after a hot dry period |
| USDA zone | 10–12 |
