The cassia fistula is a woody tree that grows to a height of 10-30 meters. Its bark is grayish-white, and its sap is reddish. The branches are relatively soft, with feather-like leaves that are 15-30 cm long.
The tree’s flowers are a vibrant yellow and highly fragrant. They grow in clusters of 20-30 blooms at the end of the branches. The fruit has a diameter of 5-7 cm and contains 2-3 small seeds inside.
In Vietnam, the cassia fistula is predominantly found in Kon Tum, Tay Ninh, Dak Lak, Gia Lai, and parts of the Southeast region. In recent years, it has become a popular choice for garden landscaping.

Soil
Although the cassia fistula is not picky about soil and is easy to grow, it is best to choose soil that is loose, rich in nutrients, and has good drainage.
Watering
The cassia fistula does not require frequent watering. Watering 3-4 times a week is sufficient, and avoid overwatering to prevent root rot.
