Senna marilandica, Wild Senna
While S. marilandica does not offer much in the way of floral nectar, however, the pollen is still quite attractive to bees. S. marilandica produces nectar through their extrafloral nectaries! These extrafloral nectaries are often visited by and highly valuable to ants. The ants have been known to protect the senna from their predators. S. marilandica are host plants to the cloudless sulphur (Phoebis sennae) butterfly as well as other species of sulphur butterflies! Due to the seed pods being particularly fibrous, they stay closed longer and make great winter snacks for birds.
