Chapman's Cassia

Chapman’s cassia is also known as Bahama senna, and is a great attractor of several sulphur butterflies. These include the cloudless sulphur, sleepy orange sulphur, little yellow, and orange barred sulphur.  The adults nectar on the yellow flowers while the caterpillars eat the leaves.

It grows to two and a half feet tall on average in full sun and likes well drained yet fertile and moist soil.  Drought is tolerated yet water may need to be added if this continues.

Chapman’s cassia is a long lived woody shrub found in the Rocklands of Dade County.  Stem borers may need treatment along with an insect that eats the flower buds.  Watch for scale insects on the stem which will kill the plant.
Try a mass planting with firebush, key’s porterweed,  and  bloodberry.  It is also a nice addition to a rock garden or a garden mimicing the Key’s.  Lignum vitae, thatch palms, quailberry, golden creeper, locust berry, and joewood make great combinations with this plant.
