Cassia Corymbosa - Yellow Senna
This is a tall, upright, fast-growing shrub with feathery leaves and a bright colorful display of large clusters of 1” golden-yellow flowers that can bloom from late summer to winter. It is normally evergreen in the Houston and surrounding areas, but is susceptible to extremely cold weather. Will sprout back if pruned after a damaging cold event. Cassia Corymbosa can grow 6’-10’ tall and can easily be pruned and trained into a small canopied tree-like shape. Both heat and drought tolerant, it is also considered as deer resistant. They are trouble-free growers which can endure a certain amount of neglect. Enjoys full sun and is a major butterfly and hummingbird nectar plant. Blooms are followed by beanlike 4- to 5-inch-long seed pods.
