Red Fountain Grass
I purchased red fountain grass 'rebrum'. Can they be left out over winter, if covered?

Unless you live in a relatively warm climate, leaving it outdoors during winter will only kill it, as these plants are warm-season grasses and do not tolerate cold. In fact, in cooler climates, they are often treated as annuals or overwintered indoors. You could try watering the plant and leaving it be (indoors) over winter (watering once a month) and put it outdoors in spring to see what happens. Unfortunately, you might need to replace it in the event that it doesn't show signs of life.
