This perennial can be hard to identify since the foliage is so similar to an iris or gladiolus but when these seed pods are present there's no question this is something different. Soon the pods will open up showing off the black round seeds inside. They are very attractive and look very much like a blackberry.
The seeds can germinate within 2-3 weeks if you provide them with moist, warm conditions or you can always divide the plant in early spring.
