My family and I just got back from a couple days in Frankenmuth, MI. I was really impressed with the gardens all through town. I'd like to plant the same kind of ornamental grass in my garden at home, but I don't know what it is. It looks like something in Fine Gardening this month called purple fountain grass (Pennisetum setaceum 'Rubrum'), but if it is, it would have to be grown as an annual. I was hoping it was hardy. Does anyone know what the grass is growing down the main street of Frankenmuth?

Thanks,

Rob
