Cassia tree info tells us that, depending on the species, these trees come in evergreen, semi-evergreen and deciduous types with brilliant pink, orange, red, white, or yellow flowers. Yellow is the most common flower type and gives the tree one of its many common names, the gold medallion tree. Each flower is only about two to three inches (5-7.5 cm.) wide but appear in clusters along densely packed racemes that on a mature growing cassia tree can reach two feet (0.5 m.) long. The light green leaves of the cassia tree are pinnate with six to twelve pairs of long oval leaflets and grow to two feet or more. Once flowering is over, the flowers are replaced with seed pods.
