About Purple Fountain Grass
While purple fountain grass is known as a perennial, it is actually considered a tender perennial. This ornamental grass cannot survive cold winters and is hardy only in USDA Plant Hardiness Zones 9 and warmer (though in Zones 7-8 it can sometimes reappear given adequate winter protection).
Does fountain grass come back every year?
It is hardy in USDA zone 8, but as a warm season grass, it will only grow as an annual in cooler areas. Fountain grass plants are perennial in the warmer climates but to save them in cooler areas try taking care of fountain grass indoors.
