Bahama cassia is a tall upright evergreen shrub that may reach a height of 3 to 9 feet. Like many other cassias, this shrub is covered with little yellow flowers in the fall and winter (and in my garden it is still blooming through spring and summer as well) which are quite attractive next to the dark green, compound leaves. This is a host plant for several sulfur butterflies, which are attracted to these 1/2- to 1-inch-wide flowers. This plant often has seedlings popping up nearby. This could be a mixed blessing by providing for a source of new plants and creating a potential weed problem.
