Cassia fistula The most famous of all Cassias, this tree has been cultivated in India for more than 2,000 years. The native range is difficult to determine as Cassia fistula has been widely cultivated for so many years. India and Egypt valued the seed pods for medicinal purposes, and it is believed that the “king of trees” in the Hindu religion is Cassia fistula. Spanish conquistadors introduced it to the West Indies and South America. Floridians and Hawaiians call it Golden Shower.
