The Senna siamea is a type of tree known by many names, including Siamese cassia, kassod tree, and cassia tree. It belongs to the legume family, which includes plants like peas and beans.
This tree originally comes from South Asia and Southeast Asia, but exactly where it first grew is a bit of a mystery.
It's a medium-sized tree that stays green all year. It can grow quite tall, up to 18 meters (about 59 feet), and has pretty yellow flowers. People often plant it to provide shade for crops like cocoa, coffee, and tea. In Thailand, the Senna siamea is a special tree for Chaiyaphum Province, and some places in the country are even named after it!
The leaves of this tree grow in a special way. They are arranged in pairs along a stem, with 6 to 12 pairs of small leaves on each stem. These leaves are rounded at both ends and have a slight reddish-green color.
