Cassia siamea, also known as the Kassod Tree, is a small tree native to Southeastern Asia. When it reaches maturity, they are often 10-20 ft. tall and just as wide, and can be grown in USDA Zones 9-11. The bright yellowish green leaves of the Kassod Tree are pinnate, made up of elliptic leaflets. In the spring, the tree erupts with panicles of yellow and orange flowers, creating a stunning display of color.
The Kassod tree is not only a pleasure to look at, but has a variety of ethnomedical uses, making it a valuable addition to any garden.
When it comes to growing and caring for your Kassod Tree, it's important to know that it thrives best in full sun but will also tolerate semi-shade. It requires regular watering, but don't overdo it! Too much water can stunt the growth of the tree. If you live in an area with temperatures that dip down to the 30s F, the Kassod Tree should be fine when mature, although it may need a bit of protection during the coldest periods. When growing the Kassod Tree in a pot, providing the roots with a bit of extra insulation can be beneficial during cold climates.
Simply put, the Cassia siamea is an excellent addition to any garden that requires minimal upkeep and provides plenty of bright color and ethnomedical uses.
