A tall native that provides the garden with bright yellow flowers in summer and attractive foliage. Not only will Senna attract pollinators, but it is also a larval host for Sulphur butterflies. The clustered flowers will form a brown seed pod that the birds will enjoy! A great choice for most conditions. This perennial can handle occasional flooding while also being drought tolerant once established. Prefers full sun to part shade, though it will produce the best flowers in more sun. Grows to be about 4-6 feet tall and 3-4 feet wide.
