Sisyrinchium angustifolium
Description
Formerly known as Sisyrinchium bermudianum, this plant features spiky, dark green, grass like foliage topped with bright purplish blue, star shaped flowers. Bloom is heaviest in late spring and early summer, though plants may continue to flower sporadically throughout the summer months. This is an excellent accent plant for walkways or rock gardens, offering a truly distinctive look. While it resembles a grass, it is actually a member of the Iris family.Photo courtesy of Walters Garden.Additional information
