Miscanthus is a great plant for screening. You can take cuttings from it every year to keep expanding the screen and after 3 or 4 years when the plants mature you can split the rhizomes and expand that way. This is my first year with any and I am really excited to see what it does on year 2 from cuttings
They don't touch them down here but they do in northern areas of MN, WI and MI in those areas use Norway spruce. Where I live bucks demolish spruce so we don't use them here.
