Wild senna was once bountiful across the New England landscape, but the population has drastically decreased in the wild.
This lovely plant is well suited for the native landscape garden with its multi-season interest. The Spring finds compound leaves gracefully unfurling as the stems grow tall and upright, while Summer brings the clusters of tiny bright yellow blossoms, highly attractive to bees and butterflies, including supporting many of the Sulphur species’.
As the blossom wane, the seed pods left behind provide both interest among the colorful leaves as well as a food source for birds of all sizes (Hello, turkeys!). The long, black pods release seeds easily, if you want to collect them it is best to pay close attention as they begin to mature.
This easy to grow plant is highly beneficial to the soil as well, and is a great option to plant in areas of disturbance, where you need a vigorous growing plant to fill in.
