This clumping, blue-green foliaged grass has amethyst-pink flowers that create fluffy, 8- to 12-inch-long plumes throughout the summer. Eventually, the flowers mature to the color of root beer foam. It is heat and drought tolerant, and it makes a fine annual in colder climates. Excellent drainage will help it thrive in humid summer climates. Not invasive from seed, ruby grass works great grown singly in pots or in groups.
