Cassia is a large genus of flowering trees and shrubs from tropical and sub-tropical regions of the world. These fast growing plants are second to none when they are in full bloom. Most species of Cassia would produce dense clusters of very attractive flowers. In fact, a Cassia in full bloom is a treat to watch. Being drought and frost tolerant, Cassias are excellent plants for gardens where they would grow fast into shrubs or mid-sized trees. Almost all species bloom and bear lovely flowers of yellow or pink colors.
How to Grow Cassia
Most species of Cassia are sun loving plants and require moderate watering in a well-drained soil. These lovely flowering plants propagate from seeds and quickly grow into young shrubs or trees.
