Purple Fountain Grasses

Question

I purchased 10 purple fountain grasses last spring.  Three were planted in big planters and the rest were planted in the ground, all in full sun and fertilized. They all grew and looked beautiful from spring to mid winter. I cut them back in late Feb. None of them have not come back. They all look like they did when I cut them back. I am trying to find out what happened. There is no green anywhere on the plants. I live in Mason, Ohio, which is 25 minutes north of Cincinnati. Is this the correct zone for this pant? This is the only thing I could think of as to why they did not survive the winter.

Answer 1

They are only hardy down to 20 degrees F. It is likely that your area is too cold for them.
