A tall, stately plant with flashy yellow flowers near the stem in July-August which give way to persistent peapod-looking fruits, Maryland Senna adds interest to a landscape all season. The leaves are large, dark-green and striking, their compound structure giving the whole plant a rather tropical look, and they're tolerant of clay and drought. Their flowers are of particular value to many species of bees, and they are also the host plant to a variety of Sulphur butterflies, including the Sleepy Orange ( Abaeis nicippe), which is exactly as adorable as it sounds (and surprisingly friendly!)
