Purchased the plant at a Tropical Audubon Society Native Plant sale. This has grown into an absolutely beautiful lush shrub with drooping branches laden with yellow flowers. This shrub is planted in full sun and does not seem to need any special care. Bought only one - will attempt to propagate more from the seed pods.

We have planted three Bahama Senna plants in the same general area. They seem to do quite well in medium to moderate shade. During mid summer in bright sunshine there was very little branch growth. It is now October and the plants are growing very well with a lot of flower buds getting ready to open. A real pretty bush/shrub/tree with lots of possibilities. We live in Zone 9A.

This plant is an excellent South Florida butterfly plant. It a larval food plant for some of the Sulphurs. It is an excellent groundcover in full sun, as it will grow in a much denser, more compact fashion in full sun than it will in a more shaded environment. In full sun, it will sprawl out across the landscape (give it plenty of room) and can be easily maintained at a height of approx. 18". The bees absolutely love the nectar. Fresh seeds germinate readily.
