The red grass is an annual here in zone 6. Pennisetum setaceum 'Rubrum'. When I saw the very little plant I thought it would not hold its color when grown but I gave it a chance. I have three of them and they are all spectacular with no care whatsoever. I'll put that one in my garden every year! The first picture shows two of them.
