Cassia Fistula Seeds - Herbal Plant

Cassia fistula, commonly known as the golden shower tree, is a deciduous ornamental tree adapted to tropical and subtropical climates. It develops an upright trunk with a spreading canopy and produces long, pendulous clusters of yellow flowers during the warm season. The tree thrives in full sun and performs best in well-drained soils, tolerating heat and dry conditions once established. It is widely used in avenue planting, gardens, and landscape settings. Seeds have a hard outer coat and benefit from scarification or soaking before sowing to improve germination, with establishment occurring steadily under warm conditions.
