Description

Mondo Grass is an ornamental grass in the asparagus family. It is an evergreen groundcover that grows up to 8-12 inches tall and is tufted. This plant blooms in the summer and has large racemes that are crowded with showy flowers held well above the foliage, which contrasts well with nearly black leaves. This evergreen groundcover spreads slowly and has some daughter plants that revert to green.

Plant in fertile, moist, slightly acidic well-drained soils in the part sun to part shade. It prefers a consistently moist environment. Use in borders, as edging, a groundcover or along stream and pond edges.

Relatively pest-free.
