Liriope spicata

 A grass-like plant that blooms! Lirope is a unique evergreen groundcover with dark green, quarter inch wide, upright foliage. Delightful, pale lavender flowers resembling grape hyacinths peak above the foliage in midsummer.

This selection spreads by underground stolons, quickly forming a thick carpet which is useful for erosion control and as a groundcover. It is also an active competitor against tree roots in the shade, making it a good choice for shady borders.
