Is there a cold hardiness limit to purple fountain grass? I planted some two years ago and it came back last year, but this year we had a colder than usual winter and I'd like to know now whether it will come back or not so I can plant other things accordingly.

It is hardy to about 20 degrees F., but if the temps there got lower than that, there is a chance the roots survived if the ground did not freeze. I would give it a few weeks to see if the roots start to grow new leaves. If you do not see any growth in a few weeks, it is likely dead.
