Answer: Your zip code places you in winter hardiness zone 4, so yes, you would need to use some of the hardiest of the ornamental grasses such as Miscanthus sinensis 'Strictus', Pennisetum alopecuroides 'Hameln', Calamagrostis x acutiflora `Karl Foerster`, Panicum virgatum 'Heavy Metal', or Calamagrostis x acutiflora `Overdam`. Your local professional nursery staff should be able to show you a selection that would grow well in your local area. These are better planted in the spring and the selection should be best at that time also. Enjoy!
