Panicum amarum 'Dewey Blue'
Bitter switchgrass is a strong and hardy native grass. An attractive variety of Panicum amarum, Dewey Blue produces small, leafy clumps of bright, blue-green evergreen foliage. In midsummer, short stems of greenish-purple inflorescences appear, with the seed heads remaining attractive well into winter. Dewey Blue thrives in dry soil and full sun, does not require much maintenance, and is suitable for use as a ground cover or for erosion control. Ideal for low-maintenance landscapes and wildlife habitats, this semi-evergreen ornamental grass is a great choice for gardeners who want a versatile, easy-care perfect specimen.
