Cassia
The Cassia tree is a fast-growing tree with beautiful bright yellow flowers that open slowly to prolong the flowering period. It is tolerant to most soils but prefers well-drained and moist areas. It requires full sunlight for the best coloring of the flowers. This tree is the national tree of Thailand.
Cassia requires water at planting but is very drought tolerant once established.
